摘要： A current sensor includes, a bus bar through which a current flows, a magnetic detection element detecting a magnetic field intensity generated by the current, first and second shielding plates arranged so as to sandwich the bus bar between the first and second shielding plates, a first conductive plate made of a conductive nonmagnetic material, arranged between the bus bar and the first shielding plate, and a second conductive plate made of the conductive nonmagnetic material, arranged between the bus bar and the second shielding plate, wherein the magnetic detection element is arranged at a first conductive plate-side. A distance between the first conductive plate and the bus bar is longer than a distance between the second conductive plate and the bus bar. The first conductive plate includes a slit formed in the first conductive plate at an overlapping position, and the slit pierces the first conductive plate.

摘要： A connector includes a first terminal housing that houses a first connecting terminal(s) and is attached to a device as an attached object thereof, and a second terminal housing that houses at least a portion of a cable(s) including a second connecting terminal(s) at an end portion thereof. The first connecting terminal(s) and the second connecting terminal(s) come into contact with each other and form a contact point(s) when the first terminal housing is fitted to the second terminal housing. The two terminal housings are fitted in a direction crossing an extending direction of the cable(s) that extends from the second terminal housing. The second terminal housing further includes a fixing means on a cable side with respect to the contact point(s) so as to fix a portion housing the cable(s) to the device or another member integrally fixed to the device.
