    摘要： A coil component includes: an insulating resin layer provided between a first planar spiral conductor formed on a back surface of a first substrate and a second planer spiral conductor formed on a back surface of a second substrate; an upper core covering a third second planer spiral conductor formed on a front surface of the first substrate on which the insulating resin layer is formed; and a lower core covering a fourth planer spiral conductor formed on a front surface of the second substrate on which the insulating resin layer is formed. One of the upper and lower cores is formed of a metal-magnetic-powder-containing resin. The coil component includes connecting portions disposed respectively at center and outside portions of each of the first and second substrates so as to physically connect the upper and lower cores.

    摘要： A device for easily determining whether a rare short circuit, which results from the generation of heat exceeding a predetermined value, has occurred in a load circuit. The device includes a fuse for detecting a load current that flows through the load circuit and generates a detection signal. A determination circuit is connected to the fuse to determine whether a rare short circuit has occurred. The determination circuit calculates one of a first parameter and a second parameter based on the detection signal. The first parameter relates to a first time period during which the load current exceeds a predetermined reference current value. The second parameter relates to a second time period during which the load current is less than or equal to the predetermined reference current value. The determination circuit cumulates one of the parameters every predetermined time interval to calculate a cumulative parameter value and determines whether a rare short circuit has occurred based on the cumulative parameter value.

    摘要： A method for manufacturing an electronic component includes: a step of temporarily bonding a substrate to a support plate with an adhesive sheet; a step of forming a cut groove for dividing the substrate into individual chips by providing the substrate with a cut extending in the thickness direction from a second surface side, located opposite the first surface side, to a certain part of the support plate; a step of forming a continuous electrode on the second surface and on a peripheral surface located inside the cut groove, of each of the chips by sputtering, for example; and a step of detaching the chips from the support plate. An electrode on the first surface of the substrate may be formed prior to the temporary bonding step, and the electrode formed on the peripheral surface may be connected to the electrode on the first surface.
