PROBLEM TO BE SOLVED: To provide an inexpensive and practical water purifying cartridge capable of efficiently utilizing a filter medium, and a water purifier. SOLUTION: The water purifier has an outer container (5) having a purified water storage part (11), an inner container (6) having a raw water storage part (10) and the water purifying cartridge 4. When the resistance of water occurring until water is issued from a discharge port (31) after being passed through the filter medium (22) of the water purifying cartridge 4 is set to [R], [R] satisfies the formula (A): 3.7×10<SP>7</SP>≤R≤9.7×10<SP>8</SP>äwherein the resistance [R] is shown by the formula: R=P×(F×μm)<SP>-1</SP>when a flaw speed is set to F(L/S), the coefficient of viscosity of water is set toμm(mPa×S) and pressure loss is set to P(mPa)}.
