摘要： A heat radiation structure of an electric apparatus provided herein is capable of readily releasing heat of electronic components to the outside and suppressing heat conduction to a rotational position sensor. A metal electromagnetic wave shielding member is fixed to a casing body of a casing. The electromagnetic wave shielding member includes a first portion that is connected to an opposed wall portion of the casing body to face a circuit substrate and a cylindrical second portion that is extending from a peripheral end of the first portion and along a peripheral wall portion of the casing body without being in contact with a housing. A heat conductive member having electrical insulating and heat conductivity properties as well as flexibility is disposed between the circuit substrate and the electromagnetic wave shielding member to closely contact both of the plurality of electronic components and the first portion of the electromagnetic wave shielding member.
