Abstract
A film pressure sensor to be interposed between a cover of an automotive seating equipment and a seat cushion material thereof and used suitably for measuring pressure to be applied to the seating equipment. A temperature sensing area (25) for sensing the temperature of a pressure sensing area (23) is formed on an insulating film (21a or 21b) of the film pressure sensor (20) using a substance whose electrical resistance changes depending on the temperature. Errors in pressure measurement to be caused by change in the temperature can be reduced or removed by utilizing the temperature determined by the temperature sensing area (25).
