Abstract
Provided is a light guide member including a light-receiving section having a light-receiving surface for receiving light of a light-emitting component, a first light guide section extending in a first extension direction from the light-receiving section, two second light guide sections branching out from the first light guide section, and two light radiation surfaces for externally emitting light guided by the two second light guide sections. The first light guide section has a first width in a first width direction that is orthogonal to the first extension direction. The first width gradually decreases as it approaches a branch point between the two second light guide sections.
