PURPOSE:To facilitate the wiring work of a LED by locating a first conductive part on the top face of a flexible board closely to the center thereof whereas locating a second conductive part closely to the periphery thereof. CONSTITUTION:A flexible board 1 is bent to form a tubular body having side faces 5A sectioning the peripheral face into 2n(n>=2) side face parts 5 wherein the 2n-th upper parts are bent at the end face part of the tubular body to provide (n) upper faces 4 forming a substantially identical plane. Conductive patterns 7-14 formed on the flexible board 1 comprise first conductive parts 15-18 formed on each upper face located closely to the center of the plane, and second conductive parts 19-22 formed closely to the periphery of the upper face 4 while being paired with the first conductive parts 15-18. Blue LEDs 42, 43, a red LED 44 and a green LED 45 are mounted at the first conductive parts 15-18 and connected with the second conductive parts 19-22 by a thin metal wire. |
