WIRING CIRCUIT BOARD, SUSPENSION, SUSPENSION WITH HEAD, HARD DISK DRIVE, AND MANUFACTURING METHOD OF WIRING CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a wiring circuit board which achieves excellent mechanical strength in a conductor layer at a terminal formation part.SOLUTION: A wiring circuit board includes: a wiring formation part; a terminal formation part for connecting with an external circuit; and an intermediate part continuously formed between the wiring formation part and the terminal formation part. The wiring formation part includes: a first insulation layer; a first conductor layer formed on the first insulation layer; a second insulation layer formed on the first conductor layer; and a second conductor layer formed on the second insulation layer so as to overlap with the first conductor layer in a thickness direction. The terminal formation part includes the first conductor layer, and a third conductor layer is formed on the first conductor layer in the terminal formation part. The third conductor layer is formed so as to contact with a surface of the second insulation layer in the intermediate part. The above object is achieved by providing the wiring circuit board.
