<p>To improve temperature distribution of fluid in a flow channel of a microfluidic device in which a resistive element disposed in substrate as that in which the channel is formed is heated to control the temperature in accordance with resistance of the element, provided is a microfluidic device including: a substrate; a flow channel disposed in the substrate for flowing through fluid therein; a first resistive element for primarily heating the fluid; and multiple second resistive elements for supplementarily heating the fluid, the elements being disposed at positions different from position where the first element is disposed. A microfluidic apparatus operating the device stores a relational expression between a temperature of the fluid and resistance of the first element, and a fixed value of a ratio between a heat energy input into the first and second element, and controls the temperature in accordance with the expression and the value.</p> |
