Abstract
A light-emitting device includes a board, a light-emitting element mounted on a surface of the board, a support member on which the board is placed, and a cover having a plate shaped main cover body covering the light-emitting element and a tubular portion which receives a light guide body that guides light emitted from the light-emitting element. The main cover body includes a base, a protrusion protruding from the base toward the board, and a ridge disposed on a protruded end of the protrusion. A step is formed by the protrusion and the ridge, and the protrusion and the ridge extend in a same direction along the base.
