SEATING SENSOR AND SEAT DEVICE

A first pressure-sensitive switch group of a seating sensor includes first pressure-sensitive switches (SW to SW) and second pressure-sensitive switches (SW to SW) located on one side of a seat in a left-right direction from the first pressure-sensitive switches, and includes a first pressure-sensitive switch pair including the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), and the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW) located between the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), a second pressure-sensitive switch pair including the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), and a third pressure-sensitive switch pair including the first pressure-sensitive switch (SW) and the second pressure-sensitive switch (SW), in which seating is detected when both the first pressure-sensitive switch and the second pressure-sensitive switch in at least one of the first to third pressure-sensitive switch pairs are turned on.
