Abstract
An inhalation device includes a nozzle, a separator, a housing, a battery portion, a circuit board, and a piezoelectric blower. The piezoelectric blower has a suction hole that opens near the center of an upper surface of the piezoelectric blower and a discharge hole that opens at the center of a bottom surface of the piezoelectric blower. The piezoelectric blower is mounted on a first main surface of the circuit board on the side of an upper housing. The circuit board applies a drive voltage to the piezoelectric blower to drive the piezoelectric blower. The circuit board has a through-hole facing the discharge hole. The through-hole overlaps the discharge hole, out of the suction hole and the discharge hole, when the first main surface of the circuit board is viewed from a front side.
