A plurality of heat generating resistors are linearly arranged and deposited in the vicinity of one of two sides orthogonal to each other on the surface of a rectangular insulating substrate, and the respective heat generating resistors are attached to the other side. Is connected to an external electric circuit by attaching a plurality of connecting terminals, and the heating resistor with the insulating substrate on its surface is moved to the back side with the heating resistor moving in a certain direction. A thermal head for printing or printing on a recording paper by sliding a heating resistor on the surface of an insulating substrate to a thermal paper or a thermal transfer ribbon, and the connecting terminals attached to one side of the insulating substrate are all of them. Is located on the front side of the arrangement position of the heating resistors with respect to the moving direction of the insulating substrate.
