Electric contact structure, process for producing the same and electronic instrument having the same

摘要

A multifunctional electronic instrument includes a body of the electronic instrument, an operation display unit movably provided on the body of the electronic instrument, and a ground structure as an electric contact structure, which includes a parallel part and a contact spring piece. The parallel part includes an electrically conductive base material and an electrically insulating surface layer formed on surfaces of both sides of the base material, and is attached to a movable member that moves together with the operation display unit. The parallel part is provided with a projection. At an end of the projection, the base material is exposed in a ruptured part where the surface layer is ruptured. The ruptured part is provided with an electric contact. The contact spring piece comes in contact with the electric contact. The base material of the parallel part and the contact spring piece are electrically connected to each other.
