Abstract
A pump device is provided. In the pump device, in a first wall portion of an insulator configured to surround an inner partition wall portion arranged on an inner peripheral side of a stator core and to prevent a winding of a driving coil from collapsing, there is provided a first notch cut out from an end surface on a Z2 direction side of the first wall portion toward a Z1 direction side. And, in a second wall portion of an insulator configured to surround an inner partition wall portion and to prevent a winding of a driving coil from collapsing, there is provided a second notch cut out from an end surface on a Z1 direction side of the second wall portion toward a Z2 direction side.
