Abstract:
1. A printed board comprising: a board; a plurality of circuit components, which are installed in the board; a wiring pattern, which electrically connects between the circuit components, the wiring pattern including at least one ground pattern; an electric regulator for supplying a predetermined amount or electricity, the electric regulator being installed in the board; a high frequency circuit, which is installed in the board and operated by the electricity, the high frequency circuit including a high frequency signal source and at least one mounting component; an electrically insulative membrane installed on an area of the board where the high frequency circuit is installed, the electrically insulative membrane including at least one component hole pattern, which surrounds one of the high frequency signal source and the mounting component, and at least one connection hole pattern; and an electrically conductive membrane installed on the electrically insulative membrane and including a component hole pattern in a position corresponding to the at least one component hole pattern of the electrically insulative membrane to surround said one of the high frequency signal source and the mounting component, wherein the electrically conductive membrane is electrically connected with the ground pattern through the connection hole pattern.
