PROBLEM TO BE SOLVED: To solve the problem that a conventional vehicular lighting fixture can obtain only a light emitting face having a narrow line shape with a constant width.SOLUTION: A vehicular lighting fixture includes: a lamp housing 10 and a lamp lens 11 which define a lamp chamber 12; and semiconductor light sources 2, 200, and a light guiding member 3 which are arranged in the lamp chamber 12. The light guiding member 3 has a light-incident surface side end part 32 at one end including a light-incident surface 30, and a light-emitting surface side end part 33 at the other end including a light-emitting surface 31, and a light guide intermediate part 34 which is an intermediate part between the light-incident surface side end part 32 and the light-emitting surface side end part 33. In at least a part of the light-emitting surface side end part 33, a wide width part 35 is provided in which the width in the thickness direction is larger than that in the light guide intermediate part 34. As a result, the vehicular lighting fixture can have a light emitting face with a wide width, and can improve the appearance of the light emitting face.
