And to avoid detection as that in spite of not being pressed actually at each intersection, has been pressed in the intersection. Input resistance and membrane Ri of the plurality of the first substrate and is formed on a second substrate which is arranged opposite to the first substrate, a plurality of intersection in a matrix so as to exist a gap for the input resistance films Ri multiple By an output resistive film Ro of, and to detect whether or not the contact state with the output resistor film Ro and the input resistive film Ri for the intersection P of the output resistive film and the input resistor film, the intersection In the matrix-type touch panel apparatus 10 for detecting that the first substrate is pressed against a second substrate at P, the voltage applying means 31 for applying a voltage of the contact detection for each input resistor films Ri, the output resistance films Ro voltage acquiring means 33 for acquiring the output voltage value from, for each intersection point P, on the basis of the output voltage value that has been acquired, the determination unit 35 whose output is, or is due to the fact that it is in contact I was equipped with.
