Claim Text:
1. A transformer comprising: a body; a first coil conductor provided in the body, and, when the first coil conductor is viewed in a plan view in a first predetermined direction, the first coil conductor spirals inwardly in a second predetermined direction; a second coil conductor provided in the body, and, when the second coil conductor is viewed in a plan view in the first predetermined direction, the second coil conductor spirals along the first coil conductor on the outside relative to the first coil conductor; a first external electrode, when viewed in a plan view in the first predetermined direction, being provided on a surface of the body in a third predetermined direction relative to a first line passing through a gravity center of the first coil conductor and an outer end of the first coil conductor, the third predetermined direction being perpendicular to the first line; a first lead-out conductor connected to the outer end of the first coil conductor and being electrically connected to the first external electrode; a second external electrode, when viewed in a plan view in the first predetermined direction, being provided on a surface of the body in a fourth predetermined direction relative to the first line, the fourth predetermined direction being opposite to the third predetermined direction; and a second lead-out conductor connected to an outer end of the second coil conductor and being electrically connected to the second external electrode, the first coil conductor and the second coil conductor spiraling along each other throughout their lengths, and by spiraling in the second predetermined direction, the first coil conductor is, at the outer end, oriented toward the fourth predetermined direction.
