PROBLEM TO BE SOLVED: To provide a landing foot detection sensor which is excellent in usability, durability, and accuracy.SOLUTION: A landing foot detection sensor comprises: a flexible mat body 2 having a shorter direction and a longer direction a first electrode wire 3 mounted inside the mat body a second electrode wire 4 mounted inside the mat body and a transmission part 5 mounted to the mat body for transmitting an electric signal. The first electrode wire and the second electrode wire are separated from each other in a normal state where no pressure is applied to the mat body. In a pressure application state where pressure is applied to the mat body, at least portions of the first electrode wire and the second electrode wire come into contact. The transmission part transmits a foot landing signal, which shows that the electrode wires are in an energization state, as a radio signal. Each of the first electrode wire and the second electrode wire comprises a plurality of shorter-direction wires along the shorter direction and a plurality of longer-direction wires connecting the plurality of shorter-direction wires with each other in the longer direction.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT
