A plurality of pressure-sensitive switches of a sitting sensor (1) has a first pressure-sensitive switch group including a first pressure-sensitive switch (SW11) including a first specific pressure-sensitive switch and a second pressure-sensitive switch (SW21), and a second pressure-sensitive switch group including first pressure-sensitive switches (SW11, SW12) including the first specific pressure-sensitive switch, and a second pressure-sensitive switch (SW22), in which in the first pressure-sensitive switch group, the first pressure-sensitive switch (SW11) and the second pressure-sensitive switch (SW21) are disposed adjacent to each other along a left-right direction of a seat (SE), in the second pressure-sensitive switch group, the first pressure-sensitive switches (SW11, SW12) and the second pressure-sensitive switch (SW22) are disposed adjacent to each other along a front-rear direction of the seat (SE), and turning on the first pressure-sensitive switch and the second pressure-sensitive switch causes a current to flow between a pair of terminals (T1, T2).
