Abstract:
Provided is a deodorizing filter which is capable of removing harmful gas components by being integrated into an electronic device such as a copier, a printer, a multifunction OA device, a computer, a projector, or a POD printing device, and which exhibits sufficient flame retardancy when burned. Specifically provided is a flame-retardant deodorizing filter formed from: an activated carbon layer which contains 30 to 200 g/m2 of activated carbon particles and 1 to 50 parts by weight of thermoplastic resin binder particles per 100 parts by weight of the activated carbon particles; and a fabric which is disposed on both sides of the activated carbon layer and which is obtained by including a phosphorus-based flame retardant to a fabric containing 20 to 10 weight% of one or more fibers selected from among a cellulose fiber, a polyvinyl alcohol fiber, a polyacryl-nitrile fiber, and a phenol fiber, such that the amount of the phosphorus-based flame retardant is 10 to 70 weight% relative to the weight of the aforementioend fabric.
