To obtain a static electricity protection structure exerting no influence of static electricity on operation of an electronic circuit including a semiconductor element.
This static electricity protection structure is equipped with a metal plate for discharging static electricity to form a static electricity discharge route between a static electricity impressing spot and the ground, in order to protect the semiconductor element carried on a printed circuit board from static electricity. When a plurality of the printed circuit boards exist in an unit case, and they have a plurality of the static electricity impressing spots, the metal plate for discharging static electricity is provided for every printed circuit board, and static electricity is discharged to the ground through a separate route for each.
