To prevent the inside of an automobile body from being seen through a lens and making vehicular lighting fixture attractive, without cost and labor and without generating a sense of incompatibility.

A leg portion 10b of a lens 10 projecting from the periphery of a front portion 10a of the lens 10 to a lamp body 2 is coupled to the opening portion in vehicular head lamp, thereby fixing the leg portion 10b to the lamp body. In the vehicular head lamp, the opening edge on the lower side of the lamp body 2 is extended from a coupled part between the leg portion 10b of the lens 10 and the lamp body 2 to the front portion 10a and the lens 10, thereby forming an extending part 9. The inside of the lower side part of the leg portion 10b is covered with the extending part 9.
