Abstract
A diaphragm-type compressor includes a substrate, an actuator, a diaphragm provided between the substrate and the actuator, and a case in which the diaphragm, the actuator, and the substrate are provided. A recessed section formed at the actuator side of the substrate and the actuator overlap in a plan view. The case has an inflow port of fluid further on the actuator side than the substrate based on the position of the diaphragm. The substrate includes a suction port for causing the recessed section to suck the fluid.
