Abstract: A second case includes a projection that projects on an opposite side of a threaded portion of the second case, which is opposite from a first case, while the projection is placed in a passage when the second case is installed to an installation-subject member. An opening is formed in a visible area of an outer peripheral surface of the projection, which is visible at a time of viewing the outer peripheral surface in a flow direction of the measurement-subject medium upon installation of the second case to the installation-subject member, and the projection includes a flow direction changing portion that changes a flow direction of the measurement-subject medium, which is introduced from the passage into an introducing hole through the opening, from a direction along the passage to a direction toward the sensor unit.
