PROBLEM TO BE SOLVED: To reduce the width of the laser-welded surface in a lamp in which a lamp body and a lens are laser-welded, and improve the appearance of the lamp which shows a dark color through the lens. SOLUTION: In the lamp in which the lamp body 1 and the lens 2 are brought in contact, and both contact surfaces 121, 231 are laser-welded, the contact surface 231 of the lens 2 does not bulge outward from the outer surface of the lens 2. Therefore, the width of a dark color portion generated by the welded surface of the lens 2 when viewed from the front through the lens 2, is reduced, thereby improving the appearance of the lamp. Besides, the laser-welded surface inclines against the contact direction of the lens 2 and the lamp body 1, thereby allowing an enlarged area of the laser-welded surface and strong weld.
