Zusammenfassung:A protruding portion 131 is formed on a surface of an optical base 110 on which a light source 101 is placed. A curing-type resin 140 is coated in a gap 132 between a light source holder 111 holding the light source and the protruding portion on the optical base, so that a sufficient securing strength is obtained against an external influence such as a drop impact by using only the curing-type resin, and heat generated from the light source can be efficiently released to the base.
