PROBLEM TO BE SOLVED: To provide the armature of a rotary electric machine that can securely and electrically insulate the mutually adjacent places of an armature coil with an excellent workability, and can form an armature core that becomes a cylindrical shape with accurate roundness, and its manufacturing method. SOLUTION: An armature core 7C is composed by forming a laminate 27 where a plurality of magnetic thin plates 28 in that a plurality of arcuate element plates 29 having a tooth piece 31 are interlocked via an interlock 30 are laminated in a cylinder shape. An armature coil 8C is formed by fitting a bobbin 34 where a coil 33 is wound to each tooth 32 where each tooth 31 is laminated. The part between the coils 33 of two adjacent bobbins 34 is electrically insulated by an insulation body 42a of an insulation sheet 42. The insulation sheet 42 is positioned by gear-locking a pair of gear-lock parts 42b and 42c projecting from the outer end of the insulation body 42a to a collar 32b outside the bobbin 34.
