An armature (11) for a miniature DC motor constitutes a rotor provided in an interior of a casing and armature windings (10) are wound around an iron core (9) in the form of a coil. In this armature (11), insulators (25, 26) made of paper including at least ordinary paper and having an electric insulation property adhere to at least portions, of both end faces of the iron core (9), on which the armature windings are wound. Thus, the iron core and the armature windings do not come into direct contact with each other.
