A motor unit includes a motor (12); and a control board configured to execute a control to drive the motor (12). The control board includes a first control board (80) and a second control board (70). The first control board (80) is provided such that a mounting space for at least one electronic component perpendicularly intersects with an extension line extending from a shaft end part (11a) of a motor shaft (11) and extends along a shaft radial direction so as to allow the at least one electronic component to be disposed along the shaft radial direction. The second control board (70) is provided such that a mounting space for at least one electronic component extends along a shaft length direction so as to allow the at least one electronic component to be disposed along the shaft length direction. The motor (12) and the control board are unitized.
