A hollow fiber type filter having a simple structure and also having an excellent heat resistance which can withstand a rapid temperature change due to high temperature generated in, for example, a steam sterilization is disclosed. The hollow fiber type filter comprises a case (2) and a plurality of hollow fiber type filter membranes (3) which are bundled and fixed with a potting material (4) in the case, wherein a stop ring (1) designed such that a thickness thereof increases inwardly is provided on an inner surface of the case into which the potting material is poured, and air release portions (5) which penetrate the stop ring in the direction of the thickness of the stop ring are formed at an appropriate portion of the stop ring. <IMAGE> |
