The present invention relates to an antibacterial deodorant with improved antibacterial, sterilization, and deodorization properties, which simplifies manufacturing while improving antibacterial, sterilization, and deodorization properties. According to the present invention, the antibacterial deodorant comprises zeolite, and a coating agent coated on a surface of the zeolite and including a base which includes diatomite, nanosilver powder, and nanotitanium powder, and a curing agent, wherein the coating agent uses water-soluble epoxy, in which the base and the curing agent are cured for 5 to 10 days, as a binder. Accordingly, the coating agent including diatomite, nanosilver powder, and nanotitanium powder having good antibacterial, sterilization, and deodorization properties is coated on the surface of the zeolite, thereby easily providing a deodorant with excellent antibacterial, sterilization, and deodorization properties. A bisphenol F-type epoxy resin and the curing agent forming the base of the coating agent are continuously cured for 5 to 10 days such that the diatomite, nanosilver powder, and nanotitanium powder included in the curing agent maintain long-time adhering force on the surface of the zeolite, thereby providing antibacterial, sterilization, and deodorization power for a long time. The base including the diatomite, nanosilver powder, and nanotitanium powder and the curing agent, which are forming the coating agent, are mixed by a weight ratio of 7:1 such that the amount of the epoxy resin is reduced to prevent pores of the diatomite and zeolite from being filled with the epoxy resin, thereby improving the antibacterial, sterilization, and deodorization power. Moreover, the coating agent is coated on the surface of the zeolite formed in a granular or ceramic ball shape such that a surface area coming in contact with fluid including air is wide, thereby increasing efficiency of the antibacterial, sterilization, and deodorization power, and air purif
