[Problem to be solved] To provide an analysis device for performing analysis using an analysis chip having therein a reaction area, wherein the temperature of the reaction area can be accurately set to a desired temperature without causing hunting. [Solution] An analysis device (1) for performing analysis relating to a substance to be detected by using an analysis chip having therein a reaction area (12) that reacts with the substance to be detected is provided. The analysis device (1) includes: a temperature control section (16, 17) in contact with the analysis chip (10); a first temperature sensor (20) for measuring an ambient temperature of the analysis chip (10); and a second temperature sensor (21) for measuring the temperature at a contact area (16a) of the temperature control section (16, 17) in contact with the analysis chip. A control circuit (22) performs feedback control of the temperature control section (16, 17) by finding a temperature of the contact area (16a) for achieving a desired temperature of the reaction area (12) based on the ambient temperature measured by the first temperature sensor (20) and a temperature gradient between a position at which the ambient temperature is measured and the reaction area (12), setting the found temperature as a target value and setting the temperature detected by the second temperature sensor (21) as an output value. |
