Abstract
An electric machine with a casing includes a circuit board arranged inside the casing and on which an electronic component is mounted, and a sealing member covering the circuit board. The sealing member includes, at a part of a boundary surface thereof coming into contact with air, a first inclined surface inclined downwardly in a vertical direction. The casing includes a front wall covering a side of the sealing member on a downward side of the first inclined surface, a rear wall covering a side of the sealing member on an upward side of the first inclined surface, and a pair of side walls covering sides of the sealing member in a direction perpendicular to a direction in which the first inclined surface is inclined. The front wall has a groove concaved from an upper side to a lower side, and the first inclined surface is inclined toward the groove.
