An embodiment of the present invention has an insulating substrate in which a first concave hole for mounting an LED chip and a second concave hole for connecting a metallic small-gauge wire are formed, where a metallic sheet that serves as a first wiring pattern is formed at a portion that includes the first concave hole, a metallic sheet that serves as a second wiring pattern is formed at a portion that includes the second concave hole, an LED chip is mounted upon the metallic sheet inside the first concave hole, the LED chip is electrically connected to the metallic sheet inside the second concave hole via a metallic small-gauge wire, and the chip-type LED is sealed with a clear resin.
