Abstract
A biochemical analysis device that emits light used to measure absorbance of a sample includes an LED that emits the light, a substrate on which the LED is mounted, a spacer that supports the substrate, a holder that accommodates the LED, the substrate, and the spacer, and a flow path formed by circulating constant temperature water through the holder. The spacer is formed of a material having a heat conductivity higher than that of the holder. The spacer is in contact with the holder at a contact portion. A convex portion of the spacer is covered with a concave portion of the holder through an air layer.
