The present invention aims to provide a long-life stator and a uniaxial eccentric screw pump provided with the stator, which enable a comparatively extended period of use by preventing damage of the stator due to repeating of attachment and removal to/from the uniaxial eccentric screw pump.
A stator 20 includes an outer cylinder 30, and a stator main body 42 having flange-shaped gasket parts 46 and 47. The stator 20 includes fixing areas 24 and 25 to which the gasket parts 46 and 47 and the outer cylinder 30 are adhered. One or both of the outer cylinder 30 and the gasket parts 46 and 47 has a derricking part penetrating or being dented in axial directions X and made into such a shape where at least part of one of the outer cylinder and the gasket parts is fitted into the other.
