A hollow fiber membrane module and potting material can be used for chemical deaeration in a semiconductor production process, in printers, in a liquid crystal sealing process or in a chemical production process. A hollow fiber membrane module 1 includes, as potting material 2, an epoxy resin cured product in which the weight change per unit surface area of a potting material test piece after immersing the test piece in a chemical for 6 months at room temperature is within the range of -20 to +20 mg/cm2,and as housing 4, a polyolefin in which the weight change per unit surface area of a test piece after immersing the test piece in a chemical for 6 months at room temperature is within the range of -20 to +20 mg/cm2,and the total metal content is 300 ppm or less. The module has a long service life when used for chemical treatment without leakage.
