Abstract
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 μm to 50 μm, and further has average surface roughness of 0.1 μm to 3 μm, a peak-to-peak concavo-convex period of 10 μm to 1000 μm, 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).
