Resistor type physical quantity sensor having migration inhibiting pattern

摘要

A physical quantity sensor e.g., temperature sensor having a resistor pattern and a ceramic support carrying the resistor pattern. The resistor pattern has an ionizing component retention conductor pattern which is branched at its negative terminal side. The resistor pattern with branched pattern are stacked between the ceramic support layers. Migration in the resistor pattern is suppressed to prevent the resistance of the resistor pattern from being increased for assuring accurate measurement of temperature. The sensor is operated without cooling to 0 DEG C.
