The contour of the inner surface (1c) of the peripheral wall (1a) of the container (1) and the contour of the purification agent containing body (3) are formed to be the same. Water which has passed through the purification agent containing body (3) is extracted from the purified-water outlet (6), while removed substances deposited in the purification agent containing body (3) is discharged from a discharge opening (7) provided in the container (1). The discharge opening (7) is provided at a position different from the position of the raw water inlet (5) and the purified-water outlet (6) of the container (1).
