PROBLEM TO BE SOLVED: To provide an optical pickup system which can keep the shape of a bent portion of a flexible printed circuit board even when the board is heated, and whose production cost is low. SOLUTION: An optical detector 12 is electrically connected with a flexible printed circuit board 20 and a bent portion 14 is formed on the flexible printed circuit board 20 at the optical detector 12 side end. The bent portion 14 has a first bent piece 14b and a second bent piece 14d each being bent at an angle of 180 degrees so that they face each other. An end of the first bent piece 14b and an end of the second bent piece 14d are disposed so as to overlap each other and fixed by soldering. Respective lands 14c, 14e of the first bent piece 14b and the second bent piece 14d are conducted by soldering, and thereby respective conductor patterns of the first bent piece 14b and the second bent piece 14d are electrically connected.
