Abstract
A physical quantity measurement device measures a physical quantity of a fluid. The device includes a passage flow channel, a branch flow channel, a flow channel partition portion that separates the passage flow channel and the branch flow channel to have the branch flow channel branch off from the passage flow channel, and a physical quantity detector. The flow channel partition portion has a partition top portion as an upstream-side end that is not exposed through the inflow port.
