Zusammenfassung:	In a drawing lamp configured to form a drawing light distribution pattern, it is possible to achieve a configuration capable of forming a clear drawing light distribution pattern. A light shielding plate 40 for shielding part of light from a light emitting element 20 to a projection lens 30 is arranged between the light emitting element 20 and the projection lens 30, and an opening 42 penetrating the light shielding plate 40 is formed in a required region of the light shielding plate 40. With this configuration, the drawing light distribution pattern can be formed as a light distribution pattern corresponding to the opening shape of the opening 42. In this configuration, the inner peripheral surface 42a of the opening 42 has such a surface shape that light emitted from the light emitting center of the light emitting element 20 does not enter the projection lens 30. Thus, even if the plate thickness of the light shielding plate 40 is increased to such an extent that the opening shape of the opening 42 is not easily deformed, occurrence of color unevenness in an outline portion of the drawing light distribution pattern due to light reflection on the inner peripheral surface 42a of the opening 42 is effectively reduced.
