摘要： A method for manufacturing a magnetic grain compact, includes: providing multiple metal grains constituted by soft magnetic alloy containing Fe, Si, and a metal element M that oxidizes more easily than Fe; compacting the metal grains; and forming oxide film formed on a surface of the metal grains, and forming first bonding parts where adjacent metal grains are directly contacted and bonded together, and second bonding parts where adjacent metal grains are bonded together via the oxide film formed around the entire surface of said adjacent metal grains other than the first bonding parts, by applying heat treatment to the compacted metal grains, thereby obtaining a magnetic grain compact.

摘要： A coil component has a magnetic body of rectangular solid shape, a coil with N turns (N is a positive number of 2 or greater) provided inside the magnetic body, an insulating intermediate part, and external electrodes. The coil has a first conductor layer, a second conductor layer, and an inter-layer connection part. The first conductor layer has a first multiple winding part which is wound around one axis with a first spacing. The second conductor layer has a second multiple winding part which is wound around the one axis with the first spacing and faces the first conductor layer. The insulating intermediate part is provided inside the magnetic body and forms, between the first conductor layer and second conductor layer, a second spacing corresponding to a thickness equal to or less than the product of the first spacing and (N−1).

摘要： A coil component includes a magnetic body part and a coil part. The magnetic body part has first and second magnetic layers stacked together alternately in one axis direction, and cover parts covering the first and second magnetic layers from the one axis direction. The coil part has conductor patterns provided on the second magnetic layers. The magnetic body part includes: oblate soft magnetic grain-containing layers extending over the entire range of the magnetic body part in the direction perpendicular to the one axis direction, exposed in the direction perpendicular to the one axis direction, and formed by oblate soft magnetic grains whose thickness direction is oriented in the one axis direction; and spherical grain-containing layers adjoining the oblate soft magnetic grain-containing layers in the one axis direction, and formed by insulative spherical grains.

摘要： A coil component is of the type where a helical coil is directly contacting a magnetic body where such coil component still meets the demand for electrical current amplification. The coil component is structured in such a way that a helical coil is covered with a magnetic body. The magnetic body is mainly constituted by magnetic alloy grains and contains substantially no glass component, and each of the magnetic alloy grains has an oxide film of the grain on its surface.
