PROBLEM TO BE SOLVED: To provide a surface treatment method capable of integrally and uniformly subjecting a plurality of materials to be treated to a surface treatment even if these materials to be treated having a bore part of an annular shape, etc. SOLUTION: The surface treatment method for a plurality of the materials to be treated consists in subjecting the materials to be treated to the surface treatment while allowing these materials to make rotation motion and/or revolution motion in a mutually spaced state in a treatment chamber. The materials to be treated are composed of supporting members 10 for surface treatment composed of freely openable and closable upper cage parts 1a and lower cage parts 1b along the longitudinal direction having many cage-like compartments 3 and planar members freely foldable along the longitudinal direction. These planar members are formed as the supporting members for surface treatment adapted in such a manner that a plurality of narrow width parts of a length corresponding to the bores of the materials to be treated may be formed in the unfolding state/or are formed to spring-like cylindrical bodies having spirally wound wire-like surfaces at both ends by winding wire-shaped members so as to have spacings. The materials to be treated are supported and housed by holders for surface treatment formed to allow the free housing of the materials to be treated in such cylindrical bodies and are subjected to the surface treatment in this state.
