  According to the multicore socket 11 of the first embodiment, the rail unit 45, 46 of the frame 41 has the contact unit 21, the insulating rod 31, the first protrusions 26, 27 of the pressing plate 51, and the second protrusions 33a, 33b. Since the third protrusions 52a and 52b are inserted and the contact unit 21 and the insulating rod 31 are simply pressed and fixed by the pressing plate 51, the assembling work is easy.

  Further, since the contact units 21 can be arranged at a narrow interval in the second direction B, the elastic body 22 can be designed compactly. Furthermore, the contact unit 21 can easily cope with a narrow pitch, and can be arranged densely in the frame 41.

  The material of the elastic body 22 is selected according to the mounting restrictions of the IC socket and the characteristics required for the contact. As an example, when a gel material is employed as the elastic body 22, assuming that the Poisson's ratio of the gel of the elastic body 22 is 0.4, the elastic body 22 having a thickness of 1.0 mm in a natural state, for example, has a thickness of 0.1 mm. When compressed by the pressing plate 51 to 5 mm, the height extends by 0.2 mm. As described above, the elastic body 22 can be connected by utilizing the vertical elongation generated by the pressing.

  The elastic body 22 is obtained by solidifying particles in a colloidal solution in a jelly shape, and employs a silicon-based or acrylic-based member. The conductor pattern 24 can be made of a thin metal plate having a large elastic modulus. As the metal material of the conductor pattern 24, nickel, nickel alloy, monel, nickel panadium, copper, phosphor bronze, or the like is employed.

  The conductor pattern 24 can be disposed by sputtering metal particles as a conductive material on the outer surface of the film 23. The conductor pattern 24 can be disposed by performing electroless plating or the like on the film 23 instead of sputtering. Note that the thickness of each conductor pattern 24 can be several microns.

  Further, when the package 61 is used at a high temperature, or when the conductor pattern 24 is required to have high durability, the elastic body 22 is desirably made of rubber having excellent durability and low compressive residual strain. When a rubber material is employed, a rubber material having silicon heat resistance is used.

  The conductor pattern 24 is formed by directly applying metal particles, which are conductive materials, to the first to third surfaces 22a, 22b, 22c and the curved surfaces 22e, 22f of the elastic body 22 without using the film 23 by sputtering. It is also possible to dispose the conductor pattern 24 by providing it or by performing electroless plating.

  The insulating rod 31, the frame 41, and the pressing plate 51 can be manufactured by molding a resin material. The pressing plate 51 may be a metal material. The metal support 25 is made of stainless steel as an example. An intermediate portion of the metal support 25 is embedded in the elastic body 22 integrally when the elastic body 22 is formed.

  In the elastic body 22 described in the first embodiment, a plurality of groove portions are formed by removing the first and second surfaces 22a and 22b and the curved surfaces 22e and 22f between the conductor patterns 24 so as to be cut out in a groove shape. In addition, the film 23 facing the groove can be cut out. When the groove is formed in this way, the deformability of the first and second transmission lines 24a and 24b constituting the electrode part of each conductor pattern 24 is improved, and stable contact with the connection object is obtained. It is done.
