PROBLEM TO BE SOLVED: To provide a light source device with an increased light volume, by effective use of even light emitted from an end part of an emission face of each LED chip.SOLUTION: Each light source device 21 is structured of an LED 31, a support body 43 consisting of a disc-shape base plate part 41 and a cylindrical tube part 42 erected at one side of the base plate part 41, and a pipe-shaped reflecting cylinder 45 insertion-coupled with an inside of the tube part 42. The LED 31 has an emission face 30 fitted inside for irradiating light of either B, G, or R, and is fixed to the support member 43 so as the emission face 30 to be parallel with the base plate part 41. The reflecting cylinder 45 has a mirror-finish cylindrical reflecting face 46 on an inside wall face, with one end side of the cylindrical reflecting face 46 inserted into the tube part 42 up to a position surrounding the LED 31 and fixed to the support member 43. Irradiated light of the LED 31 is irradiated from an irradiation opening 47 formed at the other end side of the reflecting cylinder 45. |
