A blower includes a moving blade, a motor, and a housing. The housing includes a holding portion located below the moving blade to hold the motor, and a peripheral wall portion having a cylindrical shape centered on the central axis and extending upward from a radially outer end portion of the holding portion. The peripheral wall portion includes a peripheral wall recess that is recessed downward from an upper end portion of the peripheral wall portion and connects a space radially inside of the peripheral wall portion and a space radially outside of the peripheral wall portion, and includes a first peripheral surface facing one circumferential direction that is opposite to a rotation direction of the moving blade. The first peripheral surface extends in one circumferential direction from the upper end of the peripheral wall recess toward the lower side.
