ABSTRACT:
A metal-integral conductive rubber component (10) of the present invention includes a laminate in which conductive rubber layers (1) and insulating rubber layers (2) are laminated alternately in parallel. The conductive rubber layers (1) and the insulating rubber layers (2) 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 (1) is 10−5Ω·cm or more and 10 K Ω·cm or less. The volume resistively of the insulating rubber layers (2) is 1 M Ω·cm or more and 1016Ω·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 (3) 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.
