PROBLEM TO BE SOLVED: To provide a wet heat-resistant electroconductive conjugated fiber having sufficient electroconductive performances with sight deterioration in the electroconductive performances and strength even after a wet heat treatment such as a sterilizing treatment and suitably usable for clothes uses such as working uniforms for clean rooms and medical uses, interior uses such as curtains and material uses. SOLUTION: The wet heat-resistant electroconductive conjugated fiber comprises a non-electroconductive component composed of a polyester resin and an electroconductive component composed of the polyester resin containing electroconductive particles and assumes a shape in which at least a part of the electroconductive component is exposed to the fiber surface. The conjugated fiber has 1×10<SP>4</SP>to 1×10<SP>7</SP>Ω/cm electrical resistance value,≤20 ratio of deterioration in the electroconductive performances after the wet heat treatment (treatment at 121°C for 25 h) and≥70% strength retention after the wet heat treatment (treatment at 121°C for 25 h).
