Abstract
A pump device includes a piezoelectric pump, a piezoelectric pump, and a connection pipe. The connection pipe causes a discharge port of the piezoelectric pump to be in communication with a suction port of the piezoelectric pump. The piezoelectric pump and the piezoelectric pump are disposed such that a suction-side outer wall surface in a housing of the piezoelectric pump and a suction-side outer wall surface in a housing of the piezoelectric pump face each other.
