PROBLEM TO BE SOLVED: To reduce electric power which is supplied while the quantity of light is held equal to that before division when an optical element emits the light, and prolong the life of the optical element by forming respective optical elements so that they are divided in their connection direction. SOLUTION: An element unit 3 has a base substrate 4, a circuit board 7, and an element substrate 8, which are fixed in one body. The element substrate 8 is provided with an end surface type LED 9 which is an end surface element as an optical element and, for example, every 3 of 12 end surface type LEDs 9 are connected successively as a set in array at constant intervals. Every 3 of the 12 end surface type LEDs 9 face an optical fiber 6, so this corresponds to the shape obtained by each of four light emitting elements facing four optical fibers 6 is divided into three. Namely, this optical module 1 is constituted by dividing each of four LED sets 10 emitting light beams to the four individual optical fibers 6 is divided into three end surface type LEDs 9, so the life of the LEDs 9 is prolonged. |
