Patent ID: 8274634

Claim:
A flexible printed circuit comprising: a flexible substrate including a first end section and a second end section; a first wiring layer in contact with one surface of the flexible substrate, and extending from the first end section to the second end section; a second wiring layer in contact with the surface where the first wiring layer is in contact of the flexible substrate, and extending from the first end section to the second end section; a third wiring layer in contact with the other surface of the flexible substrate, and proximate the first end section in a region opposed to the first wiring layer; a fourth wiring layer being in contact with the surface where the third wiring layer is in contact of the flexible substrate, and proximate the first end section in a region opposed to the second wiring layer; a through hole penetrating through the first end section, the second wiring layer and the fourth wiring layer; a first conductive member on surfaces proximate the through hole of the second wiring layer and the fourth wiring layer; a second conductive member on surfaces proximate the first end section of the first wiring layer and the third wiring layer; and an insulating layer in a space between the first wiring layer and the second conductive member, and the second wiring layer and the first conductive member, and a space between the third wiring layer and the second conductive member, and the fourth wiring layer and the first conductive member.
