Device comprising electrical contacts and its production process

The invention relates to a device comprising a conductive surface (12) and electrical contacts (14) by which an electric current is able to be passed. Said electrical contacts (14) comprise conductive seeds (16) deposited on the conductive surface (12), an electrically insulating layer (18), which covers discontinuously said conductive seeds (16)in order to form openings leaving access to said conductive seeds (16), and a plating layer (22) recovering said discontinuous insulating layer (18) and deposited on conductive seeds (16) which are accessible through said openings and form points from which the deposit of said plating layer (22) can start. The rest of the conductive surface (12), which doesn't comprise any electrical contacts (14), is continuously covered by said electrically insulating layer (18).
