摘要:
It is provided that a filtering medium for deodorizing filter which can sufficiently exhibit deodorizing capability and are excellent in pressure loss and dust-holding capacity while improving adhesion and rigidity. A filtering medium for deodorizing filter having a laminated structure formed by sandwiching an adsorbing layer containing an adsorbent and an adhesive between base material layers, wherein at least one layer of the base material layers is a laminate sheet obtained by integrally laminating a nonwoven fabric made of thermal-bonding-based long fibers and a needle-punched electret nonwoven fabric by needle punching; and the adsorbing layer and the nonwoven fabric made of thermal-bonding-based long fibers of the laminate sheet are laminated so as to be adjacent to each other and thermally bonded to each other.
