Pointer detection sensor and pointer detection apparatus

A pointer detection apparatus, comprising:

• a pointer detection sensor of a capacitance type, having:
• a plurality of first conductors disposed in a first direction;
• a plurality of second conductors disposed in a second direction crossing with the first direction, the plurality of first conductors and the plurality of second conductors disposed in an opposing relationship to each other and spaced apart from each other, wherein, in operation, a variation of a capacitance formed between any of the first conductors and any of the second conductors based on a variation of a distance between the first conductor and the second conductor when one of the first conductor and the second conductor is deflected by pressing by a pointer is detected to indicate a position pointed to by the pointer;
• and
• one or more spacers disposed only in regions of cross points between conductors of the plurality of first conductors and conductors of the plurality of second conductors;
• an alternating current signal supplying circuit, which, in operation, supplies an alternating current signal to one or more of the plurality of first conductors;
• and
• signal reception circuitry, which, in operation, determines a position pointed to by the pointer based on one or more signals received from the plurality of second conductors indicative of the variation of the capacitance in response to pressing corresponding to the position pointed to by the pointer.
