Abstract
A gas-permeable porous fluororesin membrane (4) made of a fluororesin is welded to a resin component (2) made of a thermoplastic resin using a welding horn (62) having a working surface (62p) adapted to be brought into contact with a work object and provided with a projection (62t). The working surface (62p) of the welding horn (62) is provided with, for example, a plurality of projections (62t). The plurality of projections (62t) may be arranged in a grid pattern on the working surface (62p).
Claims8
A method for producing a gas-permeable member, comprising welding a gas-permeable porous fluororesin membrane made of a fluororesin to a resin component made of a thermoplastic resin other than a fluororesin using a welding horn having a working surface adapted to be brought into contact with a work object, the working surface being provided with a plurality of projections, wherein
- the resin component is a support body used for a vent member for providing ventilation to an interior of a housing, a support body used for a waterproof sound-transmitting member for allowing transmission of sound while preventing entry of water, or a part of a housing.
