Claim:
A hollow fiber membrane module in which an end cap is attached to at least an end of a housing in a water-tight manner, in which an inner path is formed for processed water from the hollow fiber membrane, and at least an edge end section of the hollow fiber membrane Is fixed to the housing by a fixing member made of a fixing resin in a water-tight manner, wherein: the fixing member fixes the hollow fiber membrane on the housing; the fixing member fixes the end cop on the housing; the fixing member is solidified after fixing the hollow fiber membrane on the housing; the end cap is provided with a small lid section which is inserted in the inner path in the housing, a large lid section which contacts an end surface of the housing, and a connecting section for connecting the small lid section and the large lid section such that an area in a cross section orthogonal to a longitudinal direction of the housing is smaller than an area of the small lid section; and the fixing member is filled in a resin pouring space which is formed between an outer periphery wall of the connecting section of the end cap and an inner periphery wall of the housing.
