Description of the Related Art A connector for connecting various precision electronic devices is alternately and multiply integrated so that at least one of them has a flexible conductive member and an insulating member whose joint surfaces are parallel to each other. The following are known (see Japanese Patent Publication No. 56-48951). With respect to this industrial manufacturing method, A) at least one of the long conductive elastomer layer component and the long insulating elastomer layer component is uncured, and this layer is formed on the other elastomer sheet. While supporting, mold both components into a sheet,
B) This sheet-like body is continuously wound around a core of a rotary drum, and C) A large number of laminated bodies are cut out from the rolled-up laminated sheet-like body at a cutting surface along the radial direction. , D)
The cut-out laminated body is pressed and cured under pressure and heating to form a laminated body block in which both component layers are closely adhered and integrated. E) Thereafter, the laminated body is cut at a plane perpendicular to the laminating plane. The method of doing is proposed (Japanese Patent Publication No. 63-
(See Japanese Patent No. 37463).

などの充填剤で補強されたものとされている。In this conventional method, molding of both components of the conductive elastomer layer and the insulating elastomer layer into a sheet-like body is carried out by a calendar roll, and this insulating elastomer is used. The silicone rubber used as the raw material of the layer is reinforced with a filler such as silica powder.

ことはできないという欠点がある。However, in the molding of the sheet-shaped body by the calendar roll according to the conventional method, the thickness of the sheet-shaped body becomes large because the pinholes frequently occur when the sheet-shaped body becomes thin. If the thickness is less than 20 μm, it cannot be molded, and if the insulating elastomer layer has many pinholes, the electrical insulation cannot be maintained.
It could not be made thinner than 0 μm. Therefore, it was considered to change the method for producing the sheet-like body to a method suitable for molding a thin material such as a coater, but the insulating elastomer layer contains a reinforcing filler such as silica. Therefore, if the thickness is less than 20 μm, the filler agglomerates to cause unevenness and pinholes on the surface of the sheet. Therefore, the insulating elastomer layer has a thickness of less than 20 μm. It has the drawback that it cannot be a precision connector.

As a result of various studies to develop a high-precision connector with thin layers, the conductive elastomer layer may be formed by a conventionally known calendar roll, but the insulating elastomer layer is -Thickness is 20μ
It is preferable that the thickness is less than or equal to m, and if a conductive elastomer layer and an insulating elastomer layer made in this way are alternately laminated to form an elastic connector, a higher precision product can be obtained as compared with the conventional product. Therefore, if the insulating elastomer layer does not contain a filler such as silica, irregularities and pinholes may be formed even if the thickness is 20 μm or less in the coater. The present invention has been completed after confirming that there is not any.

Ωcm or less, and for low resistance connectors, 1Ωcm or less. It should be noted that the silicone rubber for molding this may be a millable (solid) type.
