In conventional electric power steering electric motor apparatuses, fastening and dismantling are facilitated by screws, but because spacing between a controlling circuit and a power supplying portion of an electric motor is wider, connecting terminals that project outward from a controlling circuit toward the electric motor are longer, and one problem has been that connecting positions with a power supply part of the electric motor vary, making assembly difficult. An electric power steering motor apparatus includes: an electric motor including: a stator; and a rotor that is disposed inside the stator; and a controlling unit including: a driving circuit that is connected to the stator to supply electric power; a controlling circuit that controls the driving circuit; and a housing that covers the driving circuit and the controlling circuit, and to which the electric motor can be mounted, wherein: the electric motor and the controlling unit are configured approximately coaxially; the electric power steering electric motor apparatus includes: a power supplying portion that projects outward from the electric motor; and a connecting portion that projects outward from the controlling unit, and that is connected to the power supplying portion; and the connecting portion is held on the housing by means of an insulating member.
