To provide a multi-electrode connector in which stress is alleviated that occurs in installation (insertion) of a connector and in connection under an environment in high temperature and wherein vibrations are added, and in which a stable connection state can be continuingly maintained.

The multipole connector 1 is provided with connector pins 2A-2J arranged in one direction, and these connector pins 2A-2J are coupled by insulating members 3A, 3B. In the connector pins 2A-2J, a curving part 22 curved in a dog leg shape is formed nearly at the center of stretching and extending direction on the arrangement plane. Furthermore, at the lower end side end part of the connector pins 2A-2J, an S-shaped curving part 23 is formed which is formed by folding nearly one reciprocating against the direction perpendicular to the arrangement plane. Then, at the end part of the curving part 23, the lower side horizontal part 235 extended in the direction perpendicular to the arrangement plane is made to be the lower side connection part 24, the end part extended along the arrangement plane opposed to this is made to be the upper side connection part 21, and these are joined by soldering to the lower mounting substrate and the upper mounting substrate arranged in parallel.
