Furthermore, a maximum width in an orthogonal direction to a longitudinal direction of the hollow fiber membrane is no longer than 25 mm in a cross section which is orthogonal to a longitudinal direction of the housings, and a maximum deflection in the housings which are measured according to a method for measuring the deflection according to the present invention is not more than 1% of a distance between the two housings. In such a hollow fiber membrane module, it is possible to enhance the integration ratio of the hollow fiber membrane module per a unit volume of the hollow fiber membrane module unit in which there is less deflections in the housing caused by adjust the wavelength dispersion and the dispersion slope always in minimum level automatically only by matching the position of the reflecting mirror 8, the dispersion compensation amount and the dispersion slope compensation amount which correspond to a shape of the reflecting surface 8a on the reflecting mirror 8 which is selected under such a current condition in advance. Factors such as an air bubble, and the entanglement of the hollow fiber membranes is restricted; thus, a hollow fiber membrane is not damaged. Also, in the hollow fiber membrane module, it is preferable that the housing is provided with a reinforcing rib section which strengthens the housing.
