A conductive rubber component includes a laminate in which conductive rubber layers and insulating rubber layers are laminated alternately in parallel, and the conductive rubber layers and the insulating rubber layers are integrated at their boundaries by a cross-linking reaction. A solderable metal coating is integrated with at least one surface of the laminate that is perpendicular to the electrical conduction direction by the deposition of at least one selected from atoms and molecules. This conductive rubber component can have good compression load properties and good compression set properties, achieve a stable electric connection for a long period of time due to the good compression set properties, be soldered to a printed wiring board or the like because of the presence of the integrated metal coating, suppress the occurrence of burrs, reduce costs, and improve the production efficiency.

Conductive rubber component

A metal-integral conductive rubber component () of the present invention includes a laminate in which conductive rubber layers () and insulating rubber layers () are laminated alternately in parallel. The conductive rubber layers () and the insulating rubber layers () are integrated at their boundaries by cross-linking between the conductive rubber layers and the insulating rubber layers. The volume resistivity of the conductive rubber layers () is 10&#x3a9;&#xb7;cm or more and 10 K &#x3a9;&#xb7;cm or less. The volume resistively of the insulating rubber layers () is 1 M &#x3a9;&#xb7;cm or more and 10&#x3a9;&#xb7;cm or less. A metal plate is integrated with at least one surface of the laminate that is perpendicular to the electric conduction direction via a conductive adhesive layer () made of conductive rubber. With this configuration, the metal-integral conductive rubber component can have high compression set properties, achieve a stable electric connection over a long period of time, be bonded to a printed wiring board, reduce in cost, and improve the production efficiency.
