Abstract: Provided is a cryogenic temperature measuring resistor element including a metallic temperature measuring resistor wire, an electric insulator made of a polycrystalline ceramic material, and a filler filled between the electric insulator and the temperature measuring resistor wire. The filler includes polycrystalline inorganic electric insulating powder, particles of the insulating powder being connected by glass. The glass has a lower softening point than respective melting points of the inorganic electric insulating powder, the temperature measuring resistor wire, and the electric insulator.
