摘要: PROBLEM TO BE SOLVED: To provide an electronic part housing package which is capable of firmly fixing the lead terminals effectively preventing them from bending even when the lead terminals are narrow in width and the space between the adjacent terminals is small. SOLUTION: The electronic part housing package is equipped with an insulating board 1 which is provided with a mounting pad 1a where an electronic part is mounted on its top surface, and a wiring layer 2 spreading around the mounting pad 1a and over the peripheral part is derived to serve as an inner wiring layer at the peripheral part; and a plurality of external lead terminals 4 whose ends are fixed to the upper and lower side of the peripheral edge of the insulating board 1 extending in parallel with each other. The one end of the wiring layer 2 is exposed at the peripheral part of the top surface of the insulating board 1, and a part of the external lead terminal 4 separate from its one end by a prescribed distance is electrically connected to the one end of the wiring layer 2.
