  "abstract": "A valve includes a housing, a hole, a hole, a diaphragm, a seat, and a protrusion. The housing includes a housing member and a flat board that oppose each other, and a side wall connected to the housing member and the flat board, the side wall being capable of defining a valve chamber together with the housing member and the flat board. The hole is formed in the flat board, and connects the valve chamber and an outside of the valve to each other. The hole is formed in the housing member, and connects the valve chamber and the outside of the valve to each other. The diaphragm divides the valve chamber into a first space nearer the flat board and a second space nearer the housing member, and has a through-hole that allows the first space and the second space to communicate with each other.",
