A support portion of an elastic contactor is located in a fixed region surrounded by a plurality of openings on a contact sheet. The support portion extends over the substantially entire fixed region and along the outer rims of the surrounding openings.

Contact sheet with spiral contactors serving as elastic contactors and connecting device including the same

A flexible printed circuit board includes a substrate layer composed of insulating material, a protection circuit of a thin-film capacitor element, the protection circuit including a first wiring layer on the substrate layer, a dielectric layer, and a counter electrode layer. At least a portion of each of the first wiring layer and the counter electrode layer serves as a terminal. The front surface of each of the first wiring layer and the counter electrode layer, except the terminal portion, is covered with an insulating coating.

Flexible printed circuit board

A capacitor-embedded substrate for reliably compensating for fluctuation of a power source voltage is provided. A decoupling capacitor is formed between an input side electrode layer and an output side electrode layer via interlayer insulating layers, the decoupling capacitor includes a ground layer, a power source layer, and a dielectric layer interposed therebetween. A plurality of power supply terminals used for power supply to a semiconductor device is formed by patterning the output side electrode layer and is connected to the power source layer via a capacitor via.
