摘要： A chip resistor includes a substrate, a pair of electrode elements, a resistive layer, and a protective layer. The substrate is insulating and includes a first surface, a second surface opposite the first surface and a thickness defined between the first and second surface. The electrode elements are formed on the first and spaced apart. The resistive layer is formed on the first surface and electrically connected to the electrode elements. The protective layer to covers the resistive layer. The first surface faces toward a mounting target, on which the chip resistor is mounted. Each of the electrode elements comprises an electrode layer and a conductive layer formed on the electrode layer. The boundary between the electrode layer and the conductive layer in each of the electrode elements is positioned closer to the substrate than the end surface of the protective layer in the thickness direction of the substrate.

摘要： A chip resistor of the present invention includes a substrate, a pair of electrode elements, a resistive layer, and a protective layer. The substrate is made of an insulating material and includes a first surface, a second surface opposite the first surface and a thickness defined between the first surface and the second surface. The electrode elements are formed on the first surface of the substrate and spaced apart from each other. The resistive layer is formed on the first surface of the substrate and electrically connected to the electrode elements. The protective layer is provided to cover the resistive layer. The first surface of the substrate is a mount side surface to face toward a mounting target, on which the chip resistor is mounted. Each of the electrode elements comprises an electrode layer and a conductive layer. The electrode layer is electrically connected directly to the resistive layer. The conductive layer is formed on the electrode layer. The boundary between the electrode layer and the conductive layer in each of the electrode elements is positioned closer to the substrate than the end surface of the protective layer in the thickness direction of the substrate.

摘要： A resistor comprising a substrate typically made of aluminum, a pair of top electrode layers made of a thin noble metal film disposed on both ends of the top face of the substrate, and a resistance layer of a thin metal film made of Ni system or Cr system disposed on the top face of the substrate so as to electrically connect with the top electrode layer. The moisture absorbency of a protective layer is reduced to upgrade sealing of the resistance layer by covering the resistance layer with two resin layers: a first protective layer made of polyimide resin and a second protective layer made of epoxy resin, which have different water vapor permeability, to improve the reliability, particularly the moisture resistance characteristics, of the resistor.
