The present invention relates to an activated carbon sheet, and particularly relates to an activated carbon sheet for air purification comprising activated carbon, which is suitable for removing volatile organic compounds in the passenger compartment of an automobile or the like. An object of the present invention is to provide a sheet that is excellent in toluene adsorption capacity and flame retardancy. An activated carbon sheet for air purification comprising an activated carbon fiber, granular or powdered activated carbon, and a fibrillated fiber, wherein a mass (g/m2) of the activated carbon fiber is 5 g/m2 or more, a pressure loss as measured by a method set forth below is 150 Pa or less, and a burn distance as measured by the FMVSS 302 burning test is 51 mm or less: the method is conducted in accordance with JIS B 9927:1999 "Appendix (Standard) Cleanroom - Air filters - Test methods", 3.2 "Pressure Loss Test" as follows: a piece of the activated carbon sheet cut in the form of a circle with a diameter of 110 mm is used as a measurement sample; air is sucked though the measurement sample at a linear velocity of 0.1 m/s, and a difference in static pressure between an upstream side and a downstream side of the activated carbon sheet is measured with a differential pressure gauge; and figures up to the one's place of the measured value are used as significant figures.
