Abstract
A motor includes a rotor with a shaft that extends axially, a stator that surrounds a radial outer side of the rotor, a heat sink that is axially above the stator and provided with cavities that pass conductors therethrough and extend axially, and a substrate that is axially above the heat sink and includes an electronic component mounted thereon, wherein the heat sink includes a contact surface that contacts the substrate or electronic component directly or via a heat dissipating member and an exposed surface that does not come into contact with other members, wherein the exposed surface is located closer to an outer edge than the cavities.
