Abstract
A power transistor is mounted on a metallic power supply terminal within an intake pipe , individually and separately from an electronic circuit board on which other electronic circuit element are mounted. This power supply terminal acts as a terminal for electric power input and its one portion is exposed within the gas path of the intake pipe . The heat-generation of the power transistor is effectively heat-generated by the metallic terminal without giving a remarkable effect to the other circuit elements. With this, it is possible to reduce any heat effect to the other electronic circuit components due to the self heat-generation of the power transistor without the additional number of parts and to effectuate the gas flow rate measuring apparatus of which measuring accuracy and reliability are high.
