The purposes of the present invention are to make it possible to use an LED wiring board before and after dividing the board by having the board dividable into various sizes, to simplify the dividing operation, and to simplify circuit design. Specifically, the present invention has formed thereon wiring patterns (P4, P5) for carrying currents to an LED (21), said patterns being formed in the planar direction of an LED wiring board (2), and dividing grooves (2M) for dividing the LED wiring board (2) into a plurality of elements are formed on the surface of the LED wiring board (2) in the thickness direction of the board such that the grooves traverse the wiring patterns (P4, P5) in the planar direction. The board can be used as a whole before being divided using the dividing grooves (2M), and can be also used as the divided elements by being divided along any one of the dividing grooves (2M). |
