ABSTRACT:
A resistor element includes a cylindrical, insulating ceramic substrate, a spiral resistor formed on said ceramic substrate, first and second lead wires inserted into the open ends of said ceramic substrate, a connector for making electrical connections between said resistor and said first and second lead wires, a layer of inorganic material which covers said ceramic substrate, said resistor and said connector, and a layer of resin material which covers the outer surface of said inorganic material layer. This resistor element is advantageously applied to a thermal type of flow rate sensor.
