Abstract

Provided is a pressure detection device in which a pressure detection unit includes a first connecting part that is a magnet, and the flow path unit 20 includes a resin pressure receiving diaphragm 22 and a second connecting part 23 having a magnetic material 23b. In a state where the flow path unit 20 is attached to the pressure detection unit, the first connecting part and the second connecting part 23 are arranged attracted to each other by magnetic force. The second connecting part 23 includes a resin joining member 23a in which a first joining face 23a1 joined to the pressure receiving diaphragm 22 and a second joining face 23a2 joined to the magnetic material 23b are formed at both ends in a direction along an axis Y2. The first joining face 23a1 of the joining member 23a and the pressure receiving diaphragm 22 are joined to each other by an adhesive agent, and the second joining face 23a2 of the joining member 23a and the magnetic material 23b are joined to each other by an adhesive agent.
