PROBLEM TO BE SOLVED: To provide a stator for a uniaxial eccentric screw pump easy to manufacture as compared with a conventional general stator, enable to reduce cost and weight, and to easily manufacture a large size stator. SOLUTION: A stator 5 for uniaxial eccentric screw pump has a stator main body 5' having elastic lining 4 body applied on an inner circumference surface of a female screw hole 7 having a rectangular section opening and penetrating in a longitudinal direction inserted in a cylindrical outer tube 8. In a female screw hole part 7a constituting a part in longitudinal direction of the female screw hole 7, the stator main body 5' is constituted by connecting a plurality of resin disk bodies 6 provided at a center part in series, and a gap part 9 forming an annular groove 9a of a roughly circle section is provided between connection surface inner circumference parts of the disk bodies 6.
