ABSTRACT:
A sensor for a coordinate input device includes an x-direction loop coil group including a plurality of loop coils arranged in an x direction, each loop coil having at least two linear sections perpendicular to the x direction, and a y-direction loop coil group including a plurality of loop coils arranged in a y direction, each loop coil having at least two linear sections perpendicular to the y direction. A terminal portion including a plurality of terminals is provided in the vicinity of an edge portion of the x-direction or y-direction loop coil group. Lines are disposed between the linear sections of the loop coils of the x-direction loop coil group or the y-direction loop coil group to provide connections between the terminals of the terminal portion and the corresponding loop coils of the x-direction loop coil group and the y-direction loop coil group.
