<P>PROBLEM TO BE SOLVED: To provide a micropump device exhibiting good controllability of the quantity of gas generated from a gas generating material and the pumping quantity of a micropump. Ž<P>SOLUTION: The micropump device comprises the micropump 10 and a controller 50. The micropump 10 comprises a microchannel 22 that is a liquid channel, the gas generating material 34 for generating gas by receiving irradiation of light and supplying the gas to the microchannel 22, and a light source 42 for irradiating the gas generating material 34 with light 44. The controller 50 supplies the light source 42 with a control pulse signal CS for blinking the light source 42 in a binary state by repeating a pulse sequence pattern consisting of a plurality of bits of a fixed number, each bit of which takes two states of a first level for turning on the light source 42 and a second level for turning off the light source 42.
