The thermal flowmeter includes: a sub-passage that takes a part of a gas to be measured flowing through a main passage; and a flow measurement unit disposed inside the sub-passage The sub-passage includes: a first passage provided on a measurement surface side of the flow measurement unit a second passage provided on a back surface side of the flow measurement unit and an inclined passage provided on an upstream side of an inlet of the first passage in a forward flow direction F of the gas to be measured in the first passage The inclined passage includes a first inclined surface which is inclined from the second passage side toward the first passage side with respect to the forward flow direction F, to be closer to the second passage side than the flow measurement unit",
