PROBLEM TO BE SOLVED: To provide a spiral contactor combining electric conductivity and resilience by superposing spiral contacts of projecting shape in two upper and lower stages, and having a deep yield point without increasing the occupied area of the spiral contactor. SOLUTION: The spiral contactor (1) is formed by superposing, in two upper and lower stages, the projecting spiral contacts (12, 22) formed in spiral shape from the roots toward the tip center and having the tips at the spiral center. The spiral contactor (1) is provided with the spiral contact (12) in the upper stage using material of high electric conductivity, and the spiral contact (22) in the lower stage using material of high resilience. The width of the spiral contact (22) in the lower stage is narrower than that of the spiral contact (12) in the upper stage, and the thickness of the spiral contact (22) in the lower stage is thicker than that of the spiral contact (12) in the upper stage.
