<p>PROBLEM TO BE SOLVED: To provide a microfluidic device that can measure the temperature of a fluid in a flow channel included in the microfluidic device with high accuracy and can control the temperature of the fluid.SOLUTION: A microfluidic device includes control means configured to control a temperature of a region of interest, in accordance with a value of resistance of a resistor in an expression 1 in which the value of resistance of the resistor is associated with a temperature of the region of interest. The resistor serves both as a heater for heating a fluid flowing inside a flow channel provided in a base and as a sensor for measuring a temperature of the flow channel and is provided so as to extend over a region wider than the region of interest along a longitudinal direction of the flow channel and near the flow channel. A temperature sensor for measuring a change in an ambient temperature is arranged in an outer side portion positioned in a longitudinal direction of the resistor. A temperature erroneously determined in a case where the value of resistance of the resistor in the expression 1 is affected by a change in the ambient temperature is corrected in accordance with a change in the ambient temperature measured by the temperature sensor, and the temperature of the region of interest is controlled.</p> |
