Abstract
A semiconductor light emitting device includes: a semiconductor light emitting element including a substrate and a plurality of light emitters arranged along an upper surface of the substrate; a first base disposed below a lower surface of the substrate; and a first bonding layer which bonds the semiconductor light emitting element to the first base. In the semiconductor light emitting device, a thermal conductivity of the substrate is higher than a thermal conductivity of the first bonding layer, and a thickness of the first bonding layer is less on one end side than on an other end side in an arrangement direction in which the plurality of light emitters are arranged.
