PROBLEM TO BE SOLVED: To provide a resistance sheet that detects pressing force and highly accurately detects pressing direction, and to provide a pressure-sensitive switch used for operation of any kinds of electric equipment and an input device using the same. SOLUTION: A terminal that is connected with a resistor layer of the pressure-sensitive switch is connected with a constant voltage power supply and a terminal that is connected with electrode of the pressure-sensitive switch is connected with a control means. The control means is used for estimating the pressing direction in which the resistor layer is pressed based on an input voltage that is input via the electrode of the pressure-sensitive switch in the control means. The control means generates a predetermined voltage distribution that varies in accordance with change of a direction pressed by an operator and the control means can highly accurately conduct the direction pressed by the operator, thereby obtaining the resistance sheet that is suited for the detection of the pressing detection, the pressure-sensitive switch, and the input device using the same.
