<p>[PROBLEMS] A spiral contactor where an elastic function of a spiral elastic arm is stabilized to reduce a variation in elasticity by product and that is easy to produce. [MEANS FOR SOLVING PROBLEMS] In a spiral contactor, an elastic arm (3) formed from an electric conductor such as copper is formed in a spiral shape, from a base end (4) to substantially a line O? normal to the end point of the spiral, and after that the arm is sharply bent so that a tip (5) is positioned at substantially the center of the spiral. That part of the elastic arm (3) that can be elastically deformed can be secured longer in length, so that the arm can exhibit stabilized elastic force. Also, sine there is an extensive space in the spiral elastic arm, the spiral contactor can be easily produced by etching process etc.</p> |
