Disclosed is a microfluidic device, including: a substrate; a reaction flow path formed on the substrate; and a temperature adjustment heater for heating the reaction flow path, in which a reaction flow path formation region including the reaction flow path formed therein and a temperature adjustment heater formation region including the temperature adjustment heater formed therein are alternately arranged on the substrate, the reaction flow path is formed to be bent at least one time in the reaction flow path formation region, and the temperature adjustment heater is formed to be bent at least one time in the temperature adjustment heater formation region.

In a moving structure, stability of swing motion of a moving plate is increased by enhancing tensional rigidity or flexural rigidity while restraining torsion rigidity of the hinge units. The hinge units of ladder shape with honeycombed portions are formed by twin supporting rods and crosspieces bridged between the twin supporting rods so as to support the moving plate rotatably. The tensional rigidity or the flexural rigidity is increased while restraining the torsion rigidity of the hinge units by the honeycombed portions of the hinge units.
