Abstract
Provided is a flow meter that determines a liquid flow rate based on temperature. The flow meter has a cylindrical measurement tube having an internal flow passage, and a temperature detecting substrate including a heating resistance element a temperature detecting resistance element formed on a detection surface thereof. The measurement tube has a flat surface facing the detection surface of the temperature detecting substrate, and a pair of recesses arranged so as to sandwich the internal flow passage at a position where the heating resistance element is arranged. The flat surface and the detection surface are bonded together to form two bonding area. A width of the first bonding area is narrower than a width of the second bonding area so that heat, transmitted through the measurement tube from the heating resistance element is increased.
