A vehicle lamp unit (10, 110) has a light emitting device (12) disposed adjacent to a base point (A) on an optical axis (Ax) extending in a front-rear direction of a vehicle on which the vehicle lamp unit (10, 110) is mounted, and a transparent member (14, 114) disposed in front of the light emitting device (12). The light emitting device (12) has a light emitting surface (12A) arranged to face forward. The transparent member (14, 114) is configured such that light emitted by the light emitting device (12) enters the transparent member (14, 114) and is internally reflected by a front surface (14a, 114a) of the transparent member (14, 114), and such that the light reflected by the front surface (14a, 114a) is internally reflected again by a rear surface (14b, 114b) of the transparent member (14, 114) and emitted from the front surface (14a, 114a) of the transparent member (14, 114). The front surface (14a, 114a) has a flat surface facing obliquely upward. |
