An antenna device includes an antenna coil member and an extension member. The antenna coil member includes a first base, and a spiral conductor is on a front surface of the first base. An inner-peripheral-end conductor is connected to an inner peripheral end of the spiral conductor, and an outer-peripheral-end conductor is connected to an outer peripheral end. The extension member includes a second base, and first and second extension conductor patterns are located on a front surface of the second base. First and second end-portion conductors are respectively connected to ends of the first and second extension conductor patterns. The extension member is arranged at a front surface side of the antenna coil member, the inner-peripheral-end conductor faces the first end-portion conductor, and the outer-peripheral-end conductor faces the second end-portion conductor.
