PROBLEM TO BE SOLVED: To provide a motor control device in which a temperature of a power element is less likely to increase, and to provide a motor unit including the motor control device.SOLUTION: A motor control device 40 includes: a first housing 41 formed by a metal material; a second housing which forms a housing space with the first housing 41; a motor drive part 50 including a power substrate 51 disposed on a placement surface 41B of the first housing 41 and a laminate power element mounted on the power substrate 51; and a motor control part 60 disposed on the placement surface 41B and having a control board 70 which is in a standing posture relative to the power substrate 51. The control board 70 includes: a first plane part 71; a second plane part 72; and a first bending part 74. The first plane part 71 and the second plane part 72 enclose the power substrate 51. 【課題】パワー素子の温度が高くなりにくいモータ制御装置およびこの装置を備えるモータユニットを提供する。【解決手段】モータ制御装置４０は、金属材料により形成された第１ハウジング４１と、第１ハウジング４１との間に収容空間を形成している第２ハウジングと、第１ハウジング４１の載置面４１Ｂ上に配置されたパワー基板５１およびパワー基板５１に実装された積層パワー素子を有するモータ駆動部５０と、載置面４１Ｂ上に配置され、パワー基板５１に対して立った姿勢を取る制御基板７０を有するモータ制御部６０とを備えている。制御基板７０は、第１平面部７１、第２平面部７２、および第１屈曲部７４を有している。第１平面部７１および第２平面部７２は、パワー基板５１を取り囲んでいる。【選択図】図４
