Abstract:
A thin film valve 26 is provided to a discharge port 31 formed in a plate member serving as a partition between the outside and the inside having a pressure generation source. The thin film valve 26 has: a thin film 27 closing off the outside opening of the discharge port 31; and a knife ring 28 having a through hole 32 shaped correspondingly with respect to the discharge port 31, the knife ring 28 disposed on the outside of the thin film 27. A rupturing protrusion 33 is provided to the knife ring 28 so as to project inwards. When the pressure on the inside has increased, the rupturing protrusion 33 ruptures the thin film 27.
