가공 대상에 접해야 할 작용면(62p)에 볼록부(62t)가 형성된 용착 혼(62)을 사용하여, 불소 수지로 만들어진 가스 투과성의 불소 수지 다공질막(4)을 열가소성 수지로 만들어진 수지 부품(2)에 용착한다. 용착 혼(62)의 작용면(62p)에는, 예를 들어 복수의 볼록부(62t)가 형성되어 있다. 복수의 볼록부(62t)는, 작용면(62p)에 있어서 격자 형상으로 나열되어 있어도 된다. 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).
