Abstract

A vehicle circuit panel is provided that includes a base member formed of an electrically insulating plastic material and a conducting plastic circuit path formed of an electrically conducting plastic material. The conducting plastic circuit path is formed unitarily with the base member, and is at least partially embedded in the base member, thereby forming a one-piece molded plastic member. Thus, the conducting plastic circuit path is formed into a desired circuit configuration within the base member. With the above construction, the conducting plastic circuit path can be formed into any circuit configuration, thereby increasing the degree of freedom of design of the arrangement of the circuit path.
