To provide a valve device having a configuration facilitating to cause a fixed state of a clearance between a valve body inserted in a fluid flow path and a member constituting the fluid flow path.
The valve device 1 includes a bottom 21 formed with a fluid flow path 24 and a first flow path component 20 having a body part 22 extended in a tubular shape from an outer periphery of the bottom 21. The inside of the body part 22 of the first flow path component 20 is a fluid flow path 23, into which a valve body 50 is inserted. On an inside part of an upper end of an annular flange provided on an open end of the body part 22, an annular reinforcing member 80 for reinforcing the body part 22 is attached. As the cylindricity of the body part 22 can be increased by the reinforcing member 80, the clearance between the inner peripheral surface of the body part 22 and the outer peripheral surface of the valve body 50 inserted inside the body part 22 can be held in a fixed state.
