The cap is made of a transparent material, and a cylindrical lens for correcting astigmatism of the emitted light beam is integrally formed in a portion of the cap through which the emitted light beam from the semiconductor laser passes, and the cylindrical lens is provided on the side of the cap opposite to the semiconductor laser. A light emitting device characterized by being provided with a condenser lens that condenses the light beam that passes through it.
