A light emitting device includes light transmitting resin loaded between a lens and a light emitting element. The structure of the device enables the lens to be fixed to a required position without reducing the light transmittance. The light emitting device 1 includes a light emitting element 2 and a separate lens 3 supported by a support member 4. The lens 3 is fixed to the support member 4 by hardening the resin 13 between the element 2 and the lens 3 in the support member 4. Mutually engaging male and female portions are provided between the support member 4 and the lens 3. N male portions (n is a positive integer) are provided for (n+α) female portions (α is a positive integer). The female portions allow the resin 13 to communicate with the outside of the device. The α female portions serve as a leak portion for discharging the resin 13 or bubbles to the outside when the lens 3 is fixed.
