PROBLEM TO BE SOLVED: To provide a sheath core type conjugate fiber having flame retardance and color-developing property which is the characteristic of an acrylic fiber, and a method for producing the same. SOLUTION: This sheath core type conjugate fiber is provided by consisting of a core part constituted by a vinyl chloride polymer or the vinyl chloride polymer with an acrylonitrile-based polymer and a sheath part constituted by the acrylonitrile polymer, and having (100/0) to (80/20) mass ratio of the vinyl chloride polymer to acrylonitrile-based polymer of the core part and 15 to 35 mass% chlorine content in the fiber.
