Abstract
A metal plate is supported by a base, and is disposed inside a main passage so as to be generally parallel to a direction of flow of a fluid being measured through the main passage, and a circuit board and a flow rate detecting element are disposed so as to be positioned generally in a common plane with a front surface of the metal plate. A circuit housing portion formed integrally on the base is disposed on the front surface of the metal plate so as to surround the circuit board, an electrical connection portion between the circuit board and the flow rate detecting element, and an electrical connection portion between the circuit board and a connector portion. A measuring passage groove forming portion formed integrally on the base is disposed on the front surface of the metal plate, and functions together with the metal plate to constitute a measuring passage. In addition, the circuit housing portion is charged with a sealing gel, and a cover is mounted so as to cover the circuit housing portion.
