MULTIPOLAR LEAD COMPONENT, AND CONNECTION DEVICE FOR SUBSTRATE

[Problem] To solve a deformation and a position aberration of the multipolar lead parts used in a connection with a board. [Means for solving the problem] The present invention is multipolar lead parts having plural leads and a retaining member, wherein the retaining member includes a cylindrical portion so as to cover peripheries of the leads, the cylindrical portion facing in a board direction; wherein the leads each include an upper-side board coupling portion and a lower-side board coupling portion; wherein the lower-side board coupling portion comprises a forward protruding portion that the other end side of each of the leads is bent in a direction orthogonal to an arrangement face of the leads, a vertical portion extending downward from a front end, a solder coupling portion extending backward from a lower end, and a rising portion extending upward from the solder coupling portion; and wherein a bending angle of the rising portion with respect to the solder coupling portion is formed so as to be substantially identical to a bending angle of the vertical portion with respect to the solder coupling portion.
