After the LEDs 2 (red LEDs (R), green LEDs (G) and blue LEDs (B), or white LEDs (W)) are mounted on the frame 3, without dicing the frame 3 for dividing the LEDs 2 into pieces, the tie bar is punched off to form an electric circuit. Thus, the RGB three primary color LED light source 1A or the white LED light source 1B that emits light in the state of the frame 3 can be manufactured.
