PROBLEM TO BE SOLVED: To make various kinds of light emitting colors selectable and accordingly these colors changeable with a simple constitution by constituting a light source by a plurality LED of chips different in light emitting color and arranged close to each other. SOLUTION: Wiring is made between a green(yellow) light emitting LED chip 32G bonded to the end section of the upper-side first terminal plate 41a and one end section of the upper-side second terminal plate 41b and between a green(yellow) light emitting LED chip 32G bonded to the other end section of the upper-side second terminal plate 41c and the upper-side third terminal plate 41c. Also, wiring is made between a blue light emitting LED chip 32B bonded to an end section of the lower-side first terminal plate 43a and one end section of the lower-side second terminal plate 43b and between a blue light emitting LED chip 32B bonded to the other section of the lower-side second terminal plate 43b and the lower-side third terminal plate 41c. In other words, each color light emitting chip is connected in series and to be individually driven.
