ABSTRACT:
First, second, and third lead-out conductors connected to the electrodes of two types of laser emission devices of an optical pickup are led out on a lead-out board. First connection areas short-circuit by solder at a portion of opposing parts of any two adjacent lead-out conductors of the first, second, and third lead-out conductors in the width direction crossing the longitudinal direction and open the short circuit, and second connection areas short-circuit by solder at a portion of opposing parts of the other pair of two adjacent lead-out conductors of the first, second, and third lead-out conductors in the width direction crossing the longitudinal direction and open the short circuit. The first connection areas and the second connection areas are arranged in a staggered pattern in the longitudinal direction of the lead-out conductors.
