A central support section 1 having a rectangular cross-section was arranged at a central position, and a plurality of winding support sections 2-5, 6-9 . . . of a substantially elongate platelike shape were combined and arranged around the central support section, while being sequentially swirlingly and spirally wound, and each support section was fixed in a laminated condition between inside and outside. Furthermore, the support unit bodies 15 were engaged into a fitted condition from vertical directions and connected together by adhesive, thereby forming a square pillar 16. With this, there is provided a support structure that is capable of freely setting the size of the outer diameter while securing axis of the support and obtaining a sufficient strength.
