Patent ID: 8619254

Claim:
An analysis tool used in an analysis system provided with the analysis tool including a micro flow path, a heat exchanging block capable of heating and cooling and an optical unit capable of emitting and receiving analytical light, the system in which light is radiated onto a sample located at a predetermined position in the micro flow path in a state where temperature of the micro flow path is controlled to be at a predetermined value and the analytical light from the sample is detected, the analysis tool comprising: a micro flow path chip made of resin and in which the micro flow path is formed in an inside of the micro flow path chip; and a main body of the analysis tool that holds the micro flow path chip in a detachably attached manner, wherein: the micro flow path is formed so as to cross an optical path of the light radiated from an analytical light emitting section of the optical unit in a state where the analysis tool is arranged on the heat exchanging block, and on a mount surface of the main body of the analysis tool onto which the micro flow path chip is to be mounted, a clearance section is formed in a range of the mount surface corresponding to a trajectory where the predetermined position in the micro flow path moves when the micro flow path is attached to the main body of the analysis tool, to prevent the predetermined position in the micro flow path from contacting with the mount surface.
