PURPOSE:To exactly and easily position a flexible printed circuit board (FPC) at the time of sticking the FPC to a gimbal plate. CONSTITUTION:A T-shaped positioning hole 13 consisting of a large hole part 131 and a small hole part 132 is formed on the gimbal plate 1. A broad part 21 passing the large hole part 131 of this positioning hole 13 and a base part 22 passing the small hole part 132 of the positioning hole 13 are formed on the FPC 2 formed in such a manner that the FPC can pass the inside of the positioning hole 13. the broad part 21 of this FPC is pressed to the edge of the large hole part 131 of the positioning hole 13, by which the FPC is positioned in its longitudinal direction. The base part 22 of the FPC is inserted to the inner side of the small hole part 132 of the positioning hole 13, by which the small hole part 132 is positioned in its transverse direction.
