Abstract
Provided is a micro-valve having a laminate structure capable of improving sealing performance when a foreign substance is mixed. The micro-valvehas a laminate structure and includes a base layerand a diaphragm layer. The base layer is formed with an inlet portfor introducing a gas into the micro-valve and an outlet port for allowing the gas to flow outside. The diaphragm layer is arranged to face the base layer. The diaphragm layer switches the flowing and blocking of the gas from the inlet port to the outlet port by elastic deformation thereof. The diaphragm layer has a configuration in which a plurality of deformation regionsand a plurality of rigid body regionsare alternately formed, the deformation region being elastically deformable in accordance with an inflow of a pneumatic fluid into the micro-valve. The diaphragm layer closes at least one of the inlet port and the outlet port by elastic deformation of at least a part of the plurality of deformation regions.
