A process for hermetically sealing a cap (7) to a package base (1), on which a semiconductor chip (2) is mounted, by an adhesive resin. First, the base (1) is coated with a thermosetting silicone resin (10) along a frame-shaped abutting portion, then the silicone resin is completely hardened and becomes a silicone rubber, and thereafter, the silicone rubber is coated with a thermosetting sealing resin (11) having a good adhesion with the slicone rubber. The cap is then abutted against the base, and the base and cap are heated while a pressure is exerted thereon to press the base and the cap toward each other.
