Abstract

A blowing apparatus includes a blowing unit, a first circuit board, a second circuit board, a top casing, a middle casing, and a bottom casing. The bottom casing has an intake hole. The middle casing has a nozzle to which a tube is attached, and also has an exhaust hole inside the nozzle. The exhaust hole is connected to a mask, with the tube interposed therebetween. The blowing unit includes a fan and a motor configured to rotate the fan. The blowing unit is located in a region between the first circuit board and the second circuit board. The first circuit board intersects a rotation axis of the fan. The first circuit board covers the blowing unit as viewed from the top casing in plan view of the first circuit board.
