Abstract: An electrical component having a small electrically isolating ceramic plate carrying on one of its faces a screened resistive and/or conductive pattern, the other face being in contact with a metal plate intended to be heated or the temperature of which is to be measured. The pattern has at least one metallized extremity to establish an electrical connection with a conductive wire. The conductive wire is soldered onto the metallized extremity and the small ceramic plate is entirely covered by a metal cover the peripheral edges of which surround the small plate and are fixed in a watertight manner to the metal plate by a resin. The lateral wall of the cover has at least one opening for the passage of the conductive wire or wires, the opening or openings being blocked by a sealing resin.
