PROBLEM TO BE SOLVED: To provide a deodorizing filter material in which oxidative and hydrolytic degradation of ascorbic acid and/or an ascorbic acid derivative is suppressed and simultaneously the amount of a binder to be used is reduced, when ceramic is stuck to a nonwoven fabric layer, so that the service life of the deodorizing filter material is prolonged and the amounts of the ascorbic acid and/or ascorbic acid derivative to be released are made larger.SOLUTION: The deodorizing filter material comprises a laminate which is obtained by inserting a porous material-containing layer between two nonwoven fabric layers and has three or more layers. The deodorizing filter material is obtained by sticking the ceramic, in which the ascorbic acid and/or ascorbic acid derivative are incorporated, to at least one nonwoven fabric layer of the two nonwoven fabric layers by using the acrylic resin binder.SELECTED DRAWING: None【課題】アスコルビン酸、アスコルビン酸誘導体の酸化および加水分解による劣化を抑制すると同時に、担持の際に使用するバインダー量を抑制し、長寿命でアスコルビン酸、アスコルビン酸誘導体放出量の多い脱臭ろ材を実現すること。【解決手段】２層の不織布層間に多孔質体を含む層を積層した３層以上の積層体からなる脱臭ろ材において、２層の不織布層のうちの少なくとも１層の不織布層がアスコルビン酸および／またはアスコルビン酸誘導体を含有させたセラミックスがアクリル系樹脂バインダーによって添着された不織布層である脱臭ろ材。【選択図】なし
