MICROCHEMICAL DEVICE HAVING PRESSURE-REGULATED VALVE

摘要

PROBLEM TO BE SOLVED: To provide a valve-mechanism-equipped microchemical device simple in structure, high in pressure-withstanding properties, and easy to produce. SOLUTION: There are provided a microchemical device having a pressure- regulated valve that controls the flow rate of a fluid by a diaphragm made from a product of curing of an actinic-radiation-curable composition, especially, a microchemical device in which the diaphragm is made from a material having a thickness of 1-500μm and a tensile modulus of 1-700 MPa and a method for producing the same.
