摘要：PROBLEM TO BE SOLVED: To enhance stability for detecting the seating on a seat by eliminating an external factor. SOLUTION: The presence of the seating is detected and determined by comparing an output value, as a dielectric detection value L3, taken out after outputs L1 from detecting electrodes 16 (16-1, 16-2, 16-3) self-contained within a seating area 14a of a seat cushion 14 and an output L2 from a compensation electrode 18 self-contained in a position having a peripheral member substantially same to the detecting electrode in a portion other than the seating area of the seat cushion are composed to off-set the outputs from the detecting electrodes by the output of the compensation electrode, with a preset specified determination level L4.
