Abstract
In order to provide a flow measuring device high in thermal responsiveness, the flow measuring device includes a temperature detecting element 2 for temperature detection, and a conductive metal lead frame 3 that supports and fixes the temperature detecting element. Of the metal lead frame, a part of the metal lead frame mounted with the temperature detecting element has a portion which is thinner than the thickness of the other metal lead frame or narrower than the width of the other metal lead frame.
