PROBLEM TO BE SOLVED: To effectively use spaces inside an armature, and to enhance the productivity of the armature. SOLUTION: In a slotless motor in which a plurality of smooth core armature coils 4 are arranged with insulators sandwiched between on the internal circumferential surface of its slotless armature core 3, a terminal 5 composed by stacking arc-shaped coil-connecting conductor 6a, 6b, 6c whose width and thickness are arbitrarily selectable into many layers with air gaps between in an axial direction, is arranged in the vicinity of the anti-load side end part of the armature core 3. Along with it, a smooth core armature coil 4 is connected to the terminal 5, and the armature coil 4 and terminal 5 are molded with resin 9. Consequently, it is possible to laminate coil connecting conductors whose redial breadth is suppressed by making their thickness proper, into multiple layers in the axial direction, and to form a terminal of large inside diameter, and effective use of spaces inside the armature becomes feasible.
