PROBLEM TO BE SOLVED: To arrange light emitting members including six lead pins in proximity to each other.SOLUTION: Of two semiconductor lasers arranged in an X-direction, when lead pin holes corresponding to one of the semiconductor lasers are first holes, and holes corresponding to the other are second holes, six first holes (70a to 70f) are arranged to form a parallelogram with a line segment (L2a and L2b) connecting two first holes arranged side by side in the X-direction as a first short side and a line segment (L1a and L1b) connecting three first holes arranged in an intersecting direction intersecting with the X-direction as a first long side, and six second holes (60a to 60f) are arranged to form a parallelogram with a line segment (L4a and L4b) connecting two second holes arranged side by side in the X-direction as a second short side and a line segment (L3a and L3b) connecting three second holes arranged in an intersecting direction intersecting with the X-direction as a second long side.SELECTED DRAWING: Figure 11
