Abstract
A vehicular lamp (100) includes a substrate (24), a light source (22a), a projection lens (30), and a light guidance body (40) having an incident surface (44a). A first space (201) is provided between a first region (441b) and the substrate (24), the first region (441b) including, on the incident surface (44a), a part of an outer peripheral edge of the incident surface (44a), and a second space (203) communicates with the first space (201) and is in contact with a second region (441c) including, on the incident surface (44a), the other part of the outer peripheral edge of the incident surface (44a). A width of the second space (203) is wider than a width of the first space (201) in an emission direction of the light from the light source (22a).
