1. A resin curing apparatus comprising:

  • a light source having a plurality of light emitting devices for emitting a light rays each having a predetermined wavelength;

    a condenser having a first surface on which said respective light emitting devices of said light source are closely or proximally arranged, a second surface which has a light outgoing radiation area narrower than said first surface and causes a light ray incident upon said first surface to outgo in a predetermined direction, and a dioptric member which includes a material which is filled between said first surface and said second surface, optically transparent with respect to a wavelength of a light ray emitted by each of said light emitting devices and condenses a light ray from each of said light emitting devices of said light source in an area narrower than that at the time of incidence upon said first surface to be led to said second surface; and

    a guide member for guiding a light ray condensed by said condenser to a predetermined position.
