PROBLEM TO BE SOLVED: To provide an air diffusion device capable of performing stable air diffusion regardless of the increase/decrease of an air supply amount.SOLUTION: An air diffusion device 10 comprises a combination between a support body 11 and a membrane 1. The membrane 1 is formed of a composite material wherein a reinforcing member 5 comprising a synthetic resin net is embedded inside an elastic porus body 2. Because a central part of the membrane 1 in operation is suppressed by the action of the reinforcing member 5, opening diameters of micropores become uniform in the whole elastic porus body 2, so that an air diffusion state is stabilized. |
