A gene analyzer has a structure in which a metal block, a heater installed on an outer surface of the metal block, and a heat insulator applied onto an outer surface of the heater are integrally formed, thereby miniaturizing the gene analyzer. Further, parts for light measurement, such as a light source element, a light-receiving element, a light source filter, a fluorescent filter, a light source lens, a fluorescent lens, and the like, are installed in a heat insulator light source path and a heat insulator fluorescent path formed in the heat insulator, and the paths formed in the heat insulator are aligned with a block light source path and a block fluorescent path of the metal block.
