PROBLEM TO BE SOLVED: To surely prevent water leakage by enhancing water-tightness between the bottom of a water purifier main body and a fitting groove of a base. SOLUTION: The water purifier 11 is provided with the water purifier main body 12 having a cylindrical shape with a cover, the base 13 attached to the bottom of the water purifier main body 12, and a cartridge 14 housed in the water purifier 12 filled with a filter media 28. The bottom of the water purifier main body 12 is fitted to an annular fitting groove 20 provided on the upper surface of the base 13 by inserting a first sealing material 21 to stop water between the bottom of the water purifier main body 12 and the fitting groove 20 of the base 13. In the fitting groove 20 the inner bottom part is formed in a circular-arcuate shape in the cross-section such that the inner back part becomes smaller and also the first sealing material 21 is formed in a quadrilateral shape in the cross section. Thus, a concentrated load is converged on a lower end edge of the first sealing material 21 with a press force when the bottom of the water purifier main body 12 is fitted to the fitting groove 20.
