Zusammenfassung:	Provided is a heat sensitive flow meter for measuring a flow rate of a fluid passing through a flow passage provided in an internal combustion engine, including: a filter ( 7 ) (constituted of a fixed resister ( 3 ) and a capacitor ( 4 )) for inputting a flow rate signal Vin outputted from a flow rate measurement unit installed within the flow passage to subject the flow rate signal to a predetermined filter processing; and a selection unit ( 8 ) (constituted of a fixed resister ( 2 ), an operational amplifier ( 5 ), and a diode ( 6 )) for comparing the flow rate signal Vin outputted from the flow rate detection unit and a filter signal Vf passed through the filter ( 7 ) to select the signal having a higher voltage as a new flow rate signal.
