The electric motor of this blower is composed of: an outer rotor (14) that includes a bottomed cylindrical rotor member (141) that is disposed to the inside of a fan boss and rotates integrally with the fan boss; and a stator (15) that is disposed to the inside of the bottomed rotor member. The bottomed rotor member has a rotor member bottom (141a) that constitutes the bottom portion of the bottomed rotor member, and an opening hole (141c) that is a through-hole in the axial direction of a fan axial core is formed in the rotor member bottom. The fan boss has: a fan boss bottom (211) that is disposed so as to be stacked in the axial direction with respect to the rotor member bottom and constitutes the bottom portion of the fan boss; and a bottom rib (213) that is a portion of the fan boss bottom that protrudes from the fan boss bottom toward the rotor member bottom side at a position overlapping with the opening hole in the axial direction, and promotes the discharge of air from inside the bottomed rotor membe
