Abstract: This invention is capable of improving performance of a biochemical analyzer and facilitating the maintenance. A light source includes: a first LED that emits ultraviolet light and a second LED that has a light emission spectrum different from that of the first LED, the first LED and the second LED being disposed in parallel; a reflection surface that is opposite to the first LED and reflects light of the first LED; and a dichroic surface that is opposite to the second LED, reflects light of the first LED, and allows light of the second LED to penetrate. When an optical member including the dichroic surface is made to be the dichroic prism, the reflection surface reflects light of the first LED to the second LED side, and by using light source of a configuration having a light shielding unit between a light emission surface of the second LED and a dichroic prism, entering of a light emitted from the plural LEDs as a one light beam (beam) to an optical system of latter stage of the biochemical analyzer is enabled.
