A state detecting device can efficiently remove air bubbles from a liquid no matter whether the liquid flows forwards or backwards. The state detecting device () is provided in a tube to detect a state of a liquid flowing in the tube. The state detecting device () includes: a liquid hold part () in which the liquid is stored; an inflow part () from which the liquid enters the liquid hold part (); an outflow part () from which the liquid exits from the liquid hold part (); an inlet () that is a rear end portion of the inflow part (); and an outlet () that is a front end portion of the outflow part (). Here, the inlet () and the outlet () are arranged higher than a center of the liquid hold part () in a vertical direction when the state detecting device is provided in the tube.

Provided is a pressure detection device capable of easy installation and removal of a sensor in/from a diaphragm, measurement of a pressure in a wide rage, and manufacture at a low cost while reducing a size. A sensor part (A) has: a magnet () being applied with a load produced by pressing of a diaphragm (); and a magnet cap () covering the magnet (). The diaphragm () has an intra-diaphragm magnetic body () buried therein. The intra-diaphragm magnetic body () has a protrusion part protruding from the diaphragm () so as to be in contact with the magnet (). The magnet cap () has an opening part enabling the protrusion part of the intra-diaphragm magnetic body () and the magnet () to be joined together.
