PURPOSE:To position a printed circuit board to a laser unit while keeping it easy to insert a terminal to the board and to miniaturize the whole of an optical pickup device. CONSTITUTION:A through hole 6 and a notch part 7 are formed in a printed circuit board 5 respectively to face a terminal 2a serving to position a laser unit 1 and a group of the remaining terminals 2b. The terminal 2a is registered and inserted into the through hole 6, while the group of the remaining terminals 2b is positioned at the notch part 7. Circuit parts are arranged and a wiring pattern is formed at a part of the printed circuit board 5 surrounded by the terminals 2a, 2b. |
