PROBLEM TO BE SOLVED: To provide a fiber-reinforced type hollow fiber membrane suppressed from the occurrence of pinholes in a semipermeable membrane layer. SOLUTION: The fiber-reinforced type hollow fiber membrane on the surface of a braid and the semipermeable membrane layer is formed from a liquid film forming composition containing 15-25 mass% of a polymer component (a), 40-80 mass% of a good solvent (b), 1-40 mass% of a poor solvent (c) and 1-20 mass% of inorganic fine particles (d) selected from silica, titania and alumina.
