Abstract
A light emitting device includes a light emitting unit in which a resin housing extending in one direction holds a light emitting element emitting light in a light emitting direction intersecting the one direction, a suppressing member that extends in the one direction and suppresses deformation of the housing caused by heat, the suppressing member having a linear expansion coefficient different from a linear expansion coefficient of the housing, and a fixing portion that fixes the housing and the suppressing member to each other at a position overlapping, in the light emitting direction, a neutral axis of the housing or the light emitting unit or a neutral axis of the suppressing member in the light emitting direction, at plural places separated away from each other in the one direction or in a state of extending in the one direction.
