Abstract
A circuit board includes: an input terminal for inputting a signal from an external circuit; a first land and a second land; and an electrostatic-charge absorbing conductor for absorbing an electrostatic charge. The first land is electrically connected to the input terminal. The second land is separated from the first land by a predetermined distance therebetween. A distance between the electrostatic-charge absorbing conductor and the first land is shorter than a distance between the first land and the second land. In the circuit board, the electrostatic charge is effectively absorbed into the electrostatic-charge absorbing conductor through the first land so that the electrostatic charge is prevented from negatively affecting on electric parts on the board.
