Abstract
In an electronic device structure, a high dam is formed on a circuit board so as to enclose input/output terminals of an electronic component mounted on the circuit board. The input/output terminals are projected from a body of the electronic component and connected to a printed circuit formed on the circuit board. The body is covered with a metal case.
