PROBLEM TO BE SOLVED: To provide an activated carbon sheet with excellent ozone degradation function harmful gas component removal performance and excellent flame retardance.SOLUTION: In a flame-retardant deodorizing filter, a deodorizing filter is constituted by laminating an activated carbon sheet with an activated carbon-supported cloth supporting activated carbon particles on the front surface and/or inside of a cloth that is made by fibers where at least the front surface is mainly made by a thermoplastic resin. The activated carbon-supported cloth is arranged on a flow-in side and the activated carbon sheet is arranged on a flow-out side.【課題】オゾン分解機能有害ガス成分除去性と難燃性に優れる活性炭シートを提供する。【解決手段】少なくとも表面が熱可塑性樹脂を主としてなる繊維からなる布帛の、表面および／または内部に活性炭粒子を担持する活性炭担持布帛と、活性炭シートが積層されてなる脱臭フィルタであって、前記活性炭担持布帛を流入側に配置し、活性炭シートを流出側に配置することを特徴とする難燃性脱臭フィルタ。【選択図】図１
