    摘要: To reduce a signal variation of a bridge circuit connected with a temperature sensing resistor that is caused by a strain even when the strain is generated at a diaphragm portion of a substrate installed with a heater resistor and the temperature sensing resistor. In a thermal type flow rate resistor including a substrate, a diaphragm 13 formed at the substrate, and a heat generating resistor 2 and temperature detecting resistors 7 through 10 formed on the diaphragm for detecting a flow rate of a measured fluid by heating the heat generating resistor, strain detecting resistors 11 and 12 are formed on an upstream side and on a downstream side of a flow of the measured fluid relative to the heat generating resistor on the diaphragm, an amount of a strain generated on the diaphragm is detected by the strain detecting resistors, and a flow rate signal detected by the heat generating resistor and the temperature detecting resistors is compensated for the strain based on the detected amount of the strain.

    摘要: In a structure in which peripheral part of a diaphragm section of an electrical insulating film is covered with a protective film made of an organic material, the resistor wire on the diaphragm section crosses the peripheral part of the diaphragm section. At a place where a narrow wire of a resistance temperature detector and the like crosses the peripheral part of the diaphragm section, the protective film is thinner than the other part, and the dust impact resistance is reduced. At a place where a heating resistor wire connected to a heating resistor body or resistance temperature detector wires connected to resistance temperature detector bodies cross a periphery of the diaphragm section, a film component protruding from an electrical insulating film is arranged side by side with the heating resistor wire or the resistance temperature detector wires.
