A coordinate input device includes a flat substrate portion, a plurality of strain gauges formed on one surface of the substrate portion, an operating portion disposed at about the center of the other surface of the substrate portion, and a printed board on which one surface of the substrate portion is mounted. Since a portion of the printed board opposing the strain gauges has a through hole, it is thereby opened. Therefore, even when the substrate portion is bent by tilting the operating portion, the strain gauges will not touch the printed board. Accordingly, it is possible to omit flux cleaning, to shorten the assembly time, and to reduce the cost.
