Abstract

A resonance structure includes a conductor part that expands along a first plane including a first direction and a third direction; a ground conductor that expands along the first plane; first pair conductors that electrically connect the conductor part and the ground conductor along a second direction intersecting the first plane and face each other in the first direction; and second pair conductors that electrically connect the conductor part and the ground conductor along the second direction and face each other in the third direction. The conductor part capacitively connects the first pair conductors and capacitively connects the second pair conductors. A first edge and a second edge of the conductor part intersect with each other. The first edge extends in the first direction from one conductor of the first pair conductor. The second edge extends in the third direction from one conductor of the second pair conductors.
