ABSTRACT:
An electronic apparatus comprising a printed circuit board including a circuit for inputting and outputting signals between an external apparatus through a connector which can effectively chassis-earth high frequency noise generated from a circuit of the printed circuit board due to a first conductive pattern electrically connecting the connector and the circuit of the printed circuit board, a second conductive pattern connected to a chassis-earth, and a condenser provided between one end portion of the first conductive pattern and the second conductive pattern, The width of the one end portion of the first conductive pattern between the condenser and the connector is formed to be wider than the width of the portion of the first conductive pattern between the condenser and the circuit of the printed circuit board.
