An air flow measuring device includes a housing, a sensor, and a conduction member. The housing defines a bypass flow passage through which taken-in air passes. The sensor is accommodated in the bypass passage and produces an electrical signal as a result of heat transfer between taken-in air and the sensor. The conduction member includes first and second terminals. The first terminal outputs the electrical signal produced by the sensor to outside. The second terminal supplies electric power to the sensor. The housing is provided through an assembly process and a molding process. In the assembly process, the conduction member is held by a primarily shaped product defining the bypass passage to provide an assembly. In the molding process, the assembly, with the conduction member held by the primarily shaped product, is inserted into a predetermined die and a secondary molded part is injection-molded in the die.
