Abstract
A vehicle lighting device according to an embodiment includes: a socket; a light emitting module provided on one end side of the socket and including at least one light emitting element; and an optical element provided on the one end side of the socket and facing the light emitting element. The optical element has at least one incident surface having a convex curved surface protruding toward the light emitting element side; and an exit surface facing the incident surface and provided with multiple lens portions arranged side by side. The convex curved surface is a paraboloid of revolution or a hyperboloid of revolution. A luminous intensity distribution in a first direction, orthogonal to a central axis of the vehicle lighting device, of light exiting from the exit surface differs from a luminous intensity distribution in a second direction orthogonal to the central axis and the first direction.
