Vehicular lamp

A vehicular lamp comprising:

• a light guide body;
• and
• a light source configured to emit light to be guided through the light guide body, wherein
• the light guide body includes a first light guide portion, a second light guide portion, a light incident portion, a first reflective surface, and a second reflective surface,
• the first light guide portion is a long light guide body including a front surface and a back surface opposite to the front surface and extending from a proximal end portion thereof to a distal end portion thereof,
• the second light guide portion is a long light guide body including a front surface and a back surface opposite to the front surface and extending from a proximal end portion thereof to a distal end portion thereof,
• the first light guide portion and the second light guide portion are disposed side by side,
• the light incident portion includes a light incident surface that faces the light source,
• the first reflective surface is disposed between the light incident portion and the proximal end portion of the first light guide portion,
• the second reflective surface is disposed between the light incident portion and the proximal end portion of the second light guide portion,
• of the light having entered the light incident portion through the light incident surface, light internally reflected by the first reflective surface is guided in the first light guide portion from the proximal end portion to the distal end portion of the first light guide portion while being repeatedly totally reflected between the front surface and the back surface of the first light guide portion, and light internally reflected by the second reflective surface is guided in the second light guide portion from the proximal end portion to the distal end portion of the second light guide portion while being repeatedly totally reflected between the front surface and the back surface of the second light guide portion,
• the back surface of the first light guide portion includes a plurality of first structures configured to cause the light which is being guided in the first light guide portion to exit from the front surface of the first light guide portion, and
• the back surface of the second light guide portion includes a plurality of second structures configured to cause the light which is being guided in the second light guide portion to exit from the front surface of the second light guide portion.
