Original Abstract Submitted

A physical quantity detection device (), which can be disposed in a main flow path () where a measurement target gas () flows in one direction, includes: a circuit chamber () that accommodates a circuit board (); an inflow hole () that communicates the main flow path () with the circuit chamber () and allows the measurement target gas () flowing through the main flow path () to flow into the circuit chamber (); an outflow hole () that communicates the main flow path () with the circuit chamber () and allows the measurement target gas () in the circuit chamber () to flow out to the main flow path (); and a sensor () disposed in the circuit chamber () to be at least partially located on a path () of the measurement target gas () flowing from the inflow hole () to the outflow hole ().
