Seat with seating sensor and pad for seat

Abstract

A seat with a seating sensor is provided, in which no foreign body sensation is felt at all even when a sensor for detecting seating is provided, and the seat with the seating sensor is easily manufactured. A supporting member 2 is integrally provided with a bottom face of the pad 1 .
