Abstract
A semiconductor light-emitting device is provided which includes: a wiring substrate; a semiconductor light-emitting element disposed above an upper surface of the wiring substrate; and a cap unit which covers the semiconductor light-emitting element. The wiring substrate includes: a first substrate; a first metal layer and a second metal layer that are spaced apart from each other above the first substrate; and a spacer layer disposed above the first substrate. The cap unit includes a bonding surface which is bonded to the wiring substrate. The bonding surface intersects the first metal layer and the second metal layer in a top view of the wiring substrate, and the spacer layer is disposed between the bonding surface and the first substrate, at a position different from positions of the first metal layer and the second metal layer.
