PPROBLEM TO BE SOLVED: To suppress fracture of a fluid member injection device 100 even when the pressure applied to a fluid member in the fluid member injection device 100 is high and to provide the fluid member injection device 100 which suppresses the leakage of the fluid member in the fluid member injection device 100. PSOLUTION: The fluid member injection device 100 includes a tubular member 110, a fluid member injection outlet 112, an opening 114, a first member 120 which is movably disposed in the tubular member 110 along the axial direction thereof and is reversibly deformable with respect to the axial direction, and a second member 130. The second member is composed of a main part 132 which is movably disposed in the tubular member 110 along the axial direction thereof and has a rigidity higher than that of the first member 120, and the second member adheres to the inner peripheral surface of the tubular member 110 so as to prevent the fluid member from moving in the tubular member 100 along the axial direction. The first member 120 and the second member 130 are disposed in this order from the opening 114 toward the fluid member injection outlet 112 in the tubular member 110. PCOPYRIGHT: (C)2010,JPO&INPIT
