To provide a blower capable of increasing air volume which a blower flows to the outside, and suppressing an increase in manufacturing costs.SOLUTION: A blower is equipped with a rotor 20 that can rotate about a center axis J, a stator 30 that is disposed oppositely to the rotor at an interval in a diametrical direction, an impeller portion 60 that is connected to the rotor and can rotate about the center axis, a circuit board 70 that is connected with the stator, and a case 40 that stores the rotor, the stator, the impeller portion, and the circuit board. A bottom surface 42a of the case has an air passage surface 42t configuring a part of a surface facing one side in the axial direction of an air sending passage 40a. The circuit board has an exposed surface 70f that is a surface facing the one side in the axial direction and is exposed into the air sending passage. The exposed surface configures a part of the surface turning to the one side in the axial direction of the air sending passage. In the axial direction, the exposed surface is disposed at the same position as the air passage surface.SELECTED DRAWING: Figure 3 【課題】送風機が外部に流す風量を高めることができるとともに、製造コストが増大することを抑制できる、送風機を提供する【解決手段】中心軸Ｊを中心として回転可能なロータ２０と、ロータと径方向に隙間を介して対向して配置されるステータ３０と、ロータと接続され、中心軸を中心として回転可能なインペラ部６０と、ステータと接続される回路基板７０と、ロータ、ステータ、インペラ部、および回路基板を収容するケース４０と、を備える。ケースの底面４２ｓは、送風路４０ａのうち軸方向一方側を向く面の一部を構成する風路面４２ｔを有する。回路基板は、軸方向一方側を向く面であって、送風路内に露出する露出面７０ｆを有する。露出面は、送風路のうち軸方向一方側を向く面の一部を構成する。軸方向において、露出面は、風路面と同じ位置に配置される。【選択図】図３
