A light emitting device includes: a heat dissipative board; a wiring board which adheres and is fixed to the heat dissipative board and in which a through-hole is formed; a light-emitting element which is mounted on a front surface of the heat dissipative board which is exposed through the through-hole of the wiring board; a bonding wire which connects the light-emitting element and the wiring board; and a light-reflecting member which covers a surface of an inner peripheral wall of the through-hole excluding disposition places of the light-emitting element and the bonding wire.
