An electric power reception device includes an electric power receiver that receives electric power in a non-contact manner from an electric power transmitter that is provided externally. The electric power receiver includes a first coil that is formed by winding a first coil wire with a pitch. The first coil includes a first portion and a second portion that are adjacent to the first portion with the pitch. The first portion and the second portion are arranged in a direction of arrangement. A cross section of the first coil wire that is perpendicular to a direction of extension of the first coil wire is configured such that a length of a first projection line that is obtained by projecting the cross section from the direction of arrangement onto a first imaginary plane that is perpendicular to the direction of arrangement is larger than a length of a second projection line that is obtained by projecting the cross section from a direction that is perpendicular to the direction of arrangement onto a second imaginary plane that is perpendicular to the first imaginary plane. |
