PROBLEM TO BE SOLVED: To provide a motor stator with high reliability by ensuring an insulation distance between a core and a coil, at assembly into an annular form after coil winding, in the motor stator having a plurality of core segments jointed movably. SOLUTION: An insulator serving as a resin molded product intended to insulate the coil 5 and the core segment 1 includes a protrusion to ensure an insulation distance between the core and coil in a jointed part within a slot at the time of assembly into an annular form. The protrusion enables ensuring creep distance to the core, even if coil volume is at the upper limit or uneven coil winding occurs.
