PROBLEM TO BE SOLVED: To provide a spray gun equipped with a pressure detection means which does not affect normal use, so that an operator can always recognize a correct pressure at hand because appropriate control of air spray pressure is required in order to carry out stable painting. SOLUTION: The spray gun equipped with the pressure detection means is provided with a means to introduce the pressure to a part connected to an air passageway of the spray gun(receiving the pressure). The means is kept shielded from the outside in normal use. The means is opened with a measuring instrument at the time of measuring the pressure and the pressure is measured with communicating air. When the measuring instrument is disconnected, the passageway is closed. Moreover, the pressure is detected and indicated by installing a built-in pressure sensor facing the air passageway and exposing the takeoff terminal of the sensor on the outside of the spray gun, and by retrieving sensor data by contacting the takeoff terminal at the time of the measurement.
