PROBLEM TO BE SOLVED: To provide activated carbon having large adsorption capacity for trihalomethanes from passing water and excellent adsorption characteristics for a malodorous component or a color component and a water purifier provided with the activated carbon having the adsorption characteristics for the trihalomethanes or other components and capable of purifying service water with a simple structure. SOLUTION: The activated carbon is obtained by carbonizing an activated carbon raw material containing a metal components, activating and forming fine pores having a prescribed diameter distribution and, when each content of potassium, sodium, calcium and iron per the unit weight of the activated carbon is expressed respectively by GK, GNa, GCa and Gfe, (GK+GNa)/(GCa+ GFe) is 0.6-1.7 and (GCa+GFe) is 3.2-10.5 mg/g. |
