An LED is mounted on a mounting portion of a lead frame with its light-emitting portion facing an aperture. Wires that connect the LED to lead portions of the lead frame are placed on the side on which the LED is mounted. A light-transmitting resin, which transmits light emitted from the LED, is placed on the side opposite from the LED mounted side of the lead frame. A low-stress resin, which seals the LED and the wire, is placed on the LED-mounted side of the lead frame. A crack prevention structure is constituted of bent portions that are provided at the lead portion and bent toward the LED-mounted side, low-stress resin portions located on the side opposite from the LED-mounted side with respect to the bent portions, and end portions of the light-transmitting resin put in contact with the low-stress resin portions.
