PROBLEM TO BE SOLVED: To simplify the production process of an optical head. SOLUTION: A main board 40 on which a light emitting part 41 used to generate a laser beam and a light receiving part 42 used to receive the laser beam are formed is installed at an optical unit 10 whose position is adjusted freely. In addition, a flat cable 50 is inserted into a board 20, for an actuator, installed at the optical unit 10 and into the main board 40 so as to be soldered.
