Abstract:
1. A position detecting sensor that utilizes a capacitive sensing system, the position detecting sensor including a plurality of first conductors disposed in a first direction and a plurality of second conductors disposed in a direction that intersects the first direction, the position detecting sensor being configured to detect a position indicated by an indicator by detecting a change in capacitance between the first conductor and the second conductor caused by a position indication operation of the indicator, a capacitor formed between the first conductor and the second conductor being defined by four corners, wherein: the plurality of first conductors have flexibility; a dielectric member having flexibility is provided between the plurality of first conductors and the plurality of second conductors, a first surface of the dielectric member abutting the plurality of first conductors or the plurality of second conductors; for each capacitor, two, three or four spacers are provided outside two, three, or four of the four corners that define the capacitor without touching each other and without overlapping with the capacitor, to define a space between, a second surface of the dielectric member that does not abut the plurality of second conductors or the plurality of first conductors, and the other of the plurality of first conductors or the plurality of second conductors, to which the dielectric member does not abut and which faces the second surface of the dielectric member; and an abutting area between the second surface of the dielectric member having flexibility and the plurality of second conductors or the plurality of first conductors that face the second surface is changed when the plurality of first conductors are pressed in connection with a position indication operation of the indicator to thereby cause a change in the capacitance between the plurality of first conductors and the plurality of second conductors with the flexible dielectric member interposed therebetween.
