A displacement response sensor by pushing contact is provided to be used in an automatic door, a vehicle bumper, a manometer or a weight gauge, and a pipe or an apparatus using gas for measuring the pressure of gas or liquid. A displacement response sensor by pushing contact includes a first conductive layer(131), a second conductive layer(132), a current driver(134), a switch(135), a current-voltage converter(136), a first voltage comparing determinator(137), and a second voltage comparing determinator(138). The first conductive layer and the second conductive layer are included in a contact section. A conductive material having a predetermined density is contained in a soft material having flexibility. When the conductive material is pressed, the density of the conductive material in the soft material becomes larger and the resistance value reaches zero. The first and second conductive layers are installed on the upper and lower surfaces of a semi-conductive layer respectively. The current driver is connected to the first conductive layer. The switch is connected to the current driver to operate the current driver. The current-voltage converter has an inverted input section connected to the second conductive layer. The first voltage comparing determinator has an inverted input section connected to the current-voltage converter. The second voltage comparing determinator has a non-inverted input section connected to the current-voltage converter.
