PROBLEM TO BE SOLVED: To stabilize light emitting characteristics regardless of environment for use and to improve light utilization efficiency and yield by forming a light taking-out part side and an electric connection part side by separating respectively their functions to an LED chip. SOLUTION: A silver-plated copper plate being an outer electrode 105 is embedded in a light-transmitting supporting body 101 in which a lens part is integrally molded by transfer molding. In addition, on the light-transmitting supporting body 101 being on opposite side to the lens part, a recessed part on which an LED chip 102 is arranged is formed and a recessed part in which the bottom side is projected outward is provided in the recessed part. In addition, the LED chip 102 is die-bonded in the recessed part by using a light- transmitting adhesive 104 so as to make the optical axis coincide with the lens part of the light-transmitting supporting body 101. After the die-bonding resin is cured, the outer electrode 105 exposed in the recessed part from the light-transmitting supporting body 101 and an electrode of the LED chip 102 with a gallium nitride compd. semi-conductor on a sapphire base are wire-bonded with an electrically conductive wire 103. |
