A film pressure sensitive resistor comprises conductive particles such as carbon black, a binder such as polyester resin, and spherical elastic particles having an average particle diameter of 2 mum to 50 mum, and further has average surface roughness of 0.1 mum to 3 mum, a peak-to-peak concavo-convex period of 10 mum to 1000 mum, and an elastic modulus of 800 MPa to 8000 MPa so as to have reliable quality, and excellent environmental resistance, and durability to repeated use (depressing).
