PROBLEM TO BE SOLVED: To provide an excellent antimicrobial polyester conjugated fiber which does not cause an environmental problem, has the excellent antimicrobial property, and is not discolored with time, and to provide a method for producing the antimicrobial polyester conjugated fiber excellent in spinning stability. SOLUTION: This polyester sheath-core type conjugated fiber having a sheath component/core component ratio of 10/90 to 80/20 is characterized in that the sheath component contains an inorganic antimicrobial agent carrying an antibacterial metal component which is at least partially silver component, and a silver component average content and a zinc content in the polyester conjugated fiber are 20-150 ppm and≤10 ppm, respectively, and a coefficient of fiber-fiber dynamic friction is 0.20-0.35.
