<p>A sample analyzer capable of efficiently heating only a specified portion on the surface of a disk by a simple external heating means and a disk-like sample analyzing medium. An analyzing area (3) and an optical recording area (7) are formed on a disk-like substrate (1), and a light absorbing layer (12) and light reflecting layers (11) are disposed in the analyzing area (3) to form a high temperature zone (4) and low temperature zones (5). In the high temperature zone (4), heating occurs since irradiated electromagnetic wave hits the light absorbing layer (12), and in the low temperature zone (5), a temperature rise is suppressed since the electromagnetic wave is reflected on the light reflecting layers (11) and heat conduction is increased. Accordingly, a thermal cycle can be provided to a sample liquid by feeding the specimen liquid to a flow passage (6) formed so as to alternately meander between the high temperature zone (4) and the low temperature zone (5) so that various reactions can be performed.</p> |
