PURPOSE:To suppress intrusion of moisture, by forming an element mounting part by an insulating material having excellent adhesion property with a sealing resin, and bonding and fixing the mounting part to one end of each lead in the sealing resin. CONSTITUTION:An element mounting part 6 is broadly formed by using an insulating material. The peripheral part of the mounting part is fixed to the lower surface of the end part of each lead 1 by a bonding agent and the like. An element 4 is mounted and fixed on the mounting part 6 by the bonding agent and the like. Thereafter, wire bonding and resin sealing are performed. Since the mounting part 6 is not exposed to the outside of a package directly, intrusion of moisture can be suppressed and reliability can be enhanced. |
