- a lamp body having an open portion;
a lamp front cover that covers the open portion so as to form a lamp chamber;
a light source disposed inside the lamp chamber;
a light guide disposed inside the lamp chamber and positioned on one side inside the lamp chamber following along with a shape of the lamp front cover,the light guide comprising;
a side end surface to which light emitted from the tight source is incident on one side thereof;
a light-emitting surface that emits the light that is incident from the side end surface in a predetermined direction;
a reflective back surface comprising a reflecting portion facing the light-emitting surface; and
a plurality of stippling steps having a generally conical shape disposed on the reflective back surface,wherein a central axis that passes through an apex angle of every stippling step slants toward the predetermined emission direction of the light with respect to a virtual vertical line perpendicular to the reflective back surface.

Abstract
A vehicular lamp includes a light source positioned inside a lamp chamber. The lamp chamber is formed from a lamp body fixed to a vehicle body and a front cover that covers a front open portion thereof. The vehicular lamp includes a light guide that includes a side end surface to which light emitted from the light source is incident on one side thereof; a light-emitting surface that emits the light that is incident from the side end surface in a predetermined direction; and a reflective back surface that has a reflecting portion that faces the light-emitting surface. The light guide made from translucent material that is positioned on one side inside the light chamber following along with the shape of the lamp front cover. A plurality of stippling steps that have a generally conical shape are provided on the reflective back surface of the light guide. A central axis that passes through an apex angle of every stippling step slants toward the predetermined emission direction of the light with respect to a virtual vertical line perpendicular to the reflective back surface.
