Abstract
A vehicular lamp in which bonding failure between a front lens and a lamp body is prevented while enhancing the bonding strength and improving the quality of the outer appearance around the bonded surface therebetween. An end surface of a seal leg of a front lens and a receiving surface of a lamp body are bonded through laser beam welding so as to improve the outer appearance quality of the area around the bonded surfaces. The end surface is formed on an end portion of the seal leg that is bent and extended outward at a predetermined angle with respect to the bonding direction. The laser beam is irradiated onto the receiving surface through the end portion from a direction substantially orthogonal to the end surface. The resultant permeation distance of the laser beam is made short, resulting in a sufficient amount of irradiation energy. When pressure is applied to the base end portion of the seal leg by pressing on the front lens, the end surface and the receiving surface are brought into abutment in the width direction with uniform pressure.
