1. A blower housing forming a case body of a blower including a motor, the blower housing comprising:
an opening portion configured to accommodate a stator of the motor; and
an accommodating portion formed outward of the opening portion in a radial direction in such a manner as to surround an outer periphery of the stator, the accommodating portion being configured to accommodate a winding of the stator and a solder portion where conductive wires including the winding are soldered, wherein
the accommodating portion includes: a bottom surface portion forming a surface where the conductive wires and the solder portion are placed; and an inner wall portion placed from an inner edge of the bottom surface portion in the radial direction toward a first direction in an axial direction of the stator,
the bottom surface portion includes: a first portion where the conductive wire is placed; and a second portion where the solder portion is placed,
the second portion is recessed to a position deeper than the first portion in a second direction in the axial direction, and
a dimension in the axial direction from the first portion to an upper surface of the inner wall portion is set to be greater than a thickness of the conductive wire in the axial direction and less than a thickness of the solder portion in the axial direction, and
a dimension in the axial direction from the second portion to the upper surface of the inner wall portion is set to be greater than the thickness of the solder portion in the axial direction.
