ABSTRACT:
A detection element including a cylindrical base body, an electric resistor formed on an outer peripheral surface of the base body, and lead wires attached to ends of the base body. The lead wires are electrically connected to the electric resistor. An electrically thick film is provided over end faces of the base body, an inner peripheral surface and an outer peripheral surface of the base body near each of the opposite ends of the base body, and the lead wires are electrically connected to the resistor at least through the electrically conductive thick film. A process for producing such a detecting element including forming an electric resistor on an outer periphery of a cylindrical base body; coating a paste onto end faces of the base body and inner and outer peripheral surfaces of the base body near each of the end faces; forming the electrically conductive thick film electrically connected to the electrical resistor by firing the electrically conductive thick film-forming paste; and fixing the lead wires to the end portions of the base body and forming electrically conductive portions where the lead wire is electrically connected to the electrically conductive thick film.
