摘要： A base plate containing aluminum as a main component and an electrically conductive counter plate are bonded together through the medium of an electrically conductive adhesive. Even when an oxide film is formed on the surface of the base plate, electrical continuity between the base plate and the counter plate, which are connected together through the medium of the electrically conductive adhesive, is improved by a process of applying a resistance lowering voltage, which reduces the resistance component due to the oxide film by causing a dielectric breakdown.

摘要： A disk drive device is configured such that a wall of a base plate is provided with a through hole that guides a lead from a drive unit outside. The through hole is covered by a sealing sheet having an insertion hole. The lead is guided from inside the housing via the insertion hole of the sealing sheet. The sealing sheet carries a curable resin. The curable resin, temporarily softened during a curing process, flows into a space between the base plate and the through hole and a space between the insertion hole and the lead. The curable resin is cured in this state, ensuring the airtightness of the housing.
