A vehicle luminaire includes: a board having a plate shape and including a first surface, a second surface facing the first surface, and at least one coupling portion penetrating between the first surface and the second surface; a light-emitting element provided on the first surface of the board; and a connecting portion having a plate shape, including a convex portion provided inside each coupling portion on one end portion side, and extending in a direction from the first surface toward the second surface. A tip portion of the convex portion may protrude from the first surface of the board. A distance between the tip portion of the convex portion and the first surface of the board may be larger than a distance between a light-emitting surface of the light-emitting element and the first surface of the board.
