Abstract
A flow channel structure forms a first flow channel which makes a first fluid chamber and a second fluid chamber communicate with each other therethrough. The flow channel structure includes first to third plates. The first plate includes a first through hole penetrating the first plate in a thickness direction to open to the first fluid chamber. The second plate includes a second through hole penetrating the second plate in the thickness direction to open to the second fluid chamber. The third plate includes a first connecting through hole penetrating the third plate in the thickness direction. The first connecting through hole is larger in flow channel area than each of the first and second through holes. The first and second through holes are disposed in different positions from each other as seen in the thickness direction. The first connecting through hole communicates with the first and second through holes.
