A passive element has an electrical length such that a resonance mode thereof is in a target frequency band, and first and second feed elements, each of which has an electrical length such that a resonance mode thereof is not in the target frequency band. The first feed element has a first coupling conductive part, and a first connecting conductive part, which has a continuous shape with the first coupling conductive part. The second feed element has a second coupling conductive part, and a second connecting conductive part, which has a continuous shape with the second coupling conductive part. The first coupling conductive part is disposed parallel and adjacent to the passive element. The second coupling conductive part is disposed parallel and adjacent to the passive element. The first connecting conductive part and the second connecting conductive part are disposed adjacent and parallel to each other.
