PURPOSE:To prevent the removal of sealing resin by forming a recessed part on the inner plane of a housing in an area to be the adhering plane of the housing and the sealing resin. CONSTITUTION:A groove 7 is formed on the inner side of the side plane of a housing 3 other than the plane whereupon an optical element assembly 1 is mounted. The groove 7 is filled with sealing resin 6 to the inner part. Therefore, even when the sealing resin 6 contracts at the time of hardening, the sealing resin 6 is prevented from removing from the housing since the groove 7 and the hardened sealing resin 6 filling the groove 7 are fitted. |
