Light source device and projector

Abstract

A light source device according to an aspect of the present disclosure includes a light source unit including a light emitting element configured to emit light, a light guide member on which the light emitted from the light emitting element is made incident, the light guide member emitting the light, and a support member configured to support the light guide member. The support member includes a support surface facing a first direction intersecting a longitudinal direction, which is a direction in which the light guide member extends, and configured to support the light guide member, a heat transfer member extending in a second direction intersecting the longitudinal direction, and a holding section configured to hold the heat transfer member, the heat transfer member is disposed on the inside of the holding section, and the thermal conductivity of the heat transfer member is higher than the thermal conductivity of the holding section.

Dependencies are inferred from the claim text.
