Patent ID: 8714000

Claim:
An air flow measuring device for taking in a part of air flowing through a predetermined passage to produce an electrical signal that is in accordance with a flow rate of air in the passage, the device comprising: a housing defining a bypass flow passage through which the taken-in air passes; a sensor accommodated in the bypass flow passage and configured to produce the electrical signal as a result of a heat transfer between the taken-in air and the sensor; and a conduction member including: a first terminal configured to output the electrical signal produced by the sensor to an outside of the sensor; and a second terminal configured to supply electric power to the sensor, wherein the first terminal and the second terminal are held by a recess part of a primarily shaped product or a projection part of the primarily shaped product to provide an assembly, the primarily shaped product defining the bypass flow passage; and the assembly is insert-molded with a secondary molded part.
