Abstract
The present invention addresses the problem of obtaining a thermal flow meter capable of reducing a pulsation error by preventing a discharge port and a main outlet from being blocked by a vortex during a transient period and reducing a difference between flow speed distributions in normal and pulsation states. This thermal flow meter is provided with a housing disposed in a main passage; and a sub passage provided in the housing. In addition, in the housing, a first outlet and a second outlet of the sub passage are disposed in a downstream end portion of the housing, and a curved surface section is provided adjacent to the first and second outlets.
