PROBLEM TO BE SOLVED: To provide a stator enabling relatively easy winding work even in a motor configuration that makes winding work difficult and ensuring excellent winding workability and the like. SOLUTION: The stator 1 is applied to inner-rotor brushless motors. It is provided with 12N (N is an integer not less than 1) tooth portions 8 and its core 5 is formed by coupling multiple bendable split cores 50. Each of the split cores 50 includes four element tooth portions 80 constituting a tooth portion 8 and arranged in line. In each element tooth portion 80 of each split core 50, four element coils 70 forming a coil are continuously formed by one conductive wire 10. Each element coil 70 of each split core 50 includes a first element coil wound clockwise and a second element coil wound counterclockwise as viewed from the tip of the element tooth portion 80. The first element coils and the second element coils are identical in arrangement in each split core 50. COPYRIGHT: (C)2010,JPO&INPIT
