A first RF radiating element is transmissive to visible light and includes a first electrode and a second electrode. The first electrode is formed of at least one linear conductor. The second electrode is formed of a material having a visible light transmittance greater than the visible light transmittance of a material forming the first electrode. The conductivity of the second electrode is smaller than the conductivity of the first electrode. The first electrode and the second electrode face each other in a stacking direction. The first RF radiating element includes a first region, in which the first electrode overlaps the at least one linear conductor, and a second region, in which the first electrode does not overlap the at least one linear conductor, in plan view of the first RF radiating element in the stacking direction.
