PROBLEM TO BE SOLVED: To provide a connection device capable of stabilizing contact of an external connection part (spherical contact) of an electric component to a spiral contact thereof. SOLUTION: The winding directions of the spiral contacts 20 adjacent to each other are set opposite to each other. Alternatively, when the winding directions of the spiral contacts 20 adjacent to each other are set opposite to each other, and formation positions of winding start ends of the spiral contacts 20 adjacent to each other are so formed as to be different from each other by 180°, tensile stress between the spiral contacts 20 adjacent to each other can be canceled. Thereby, distortion generated in a board or the like with the spiral contacts 20 formed can be minimized, so that contact between the spherical contact and the spiral contact 20 can be stabilized.
