PROBLEM TO BE SOLVED: To obtain a conjugate binder fiber suitable for nonwoven fabrics for hygienic materials and having antimicrobial property with high durability by arranging a polyester-based resin in the core part and arranging a polyolefin- based resin, to which a specific phosphite is added, having lower melting point than that of the above polyester in the sheath part. SOLUTION: This antimicrobial conjugate binder fiber is obtained by carrying out conjugate spinning so that a polyester-based resin having >=150 deg.C melting point, e.g. polyethylene terephthalate is arranged in the core part and a polyolefin-based resin such as polyethylene or polypropylene having a melting point lower by >=20 deg.C than that of the above polyester-based resin is arranged in the sheath part.
