Abstract

PURPOSE: To enable a device to withstand a gread number of times of attaching into and detaching from a key hole with the deformation of a lead prevented, by providing an eternal lead terminal into a sealing resin body without protruding it out of the sealing resin body and by making one part of the lead surface exposed in contact with the key-hole contact of the electronic key.
CONSTITUTION: At the tip in the center of the frame of element mount lead 3 connected to the frame of the lead frame, mount 6 for mounting a semiconductor element is formed. Leads 1 to 5 connected at respective one-side terminals to the frame in parallel to lead 3 are elongated near mount part 6, with curved parts made partially, and made into contacts 1' to 5' while being protruded to the top surface or reverse surface of the frame. In addition, sealing-resin reinforcing metal part 7 is also formed facing to mount part 6. The frame is constituted in this way, an element is fixed to mount part 6, and electrodes are connected to respective leads; and then, only contacts 1' to 5' are exposed, resin sealing is done, and unneeded parts of the frame is removed by being cut off.
