PURPOSE: A showcase of a honeycomb structure is provided to manufacture a showcase in a honeycomb structure by providing 'Y'-shaped and '<'-shaped connecting members for diagonally connecting straight-type pipes in a hexagonal shape. CONSTITUTION: The showcase is manufactured by connecting straight-type pipes(2) by a screw clamping force of engaging bolts in a state that connecting members with semi-circle portions formed in two or three directions are symmetrically contacted with each other and the ends of the straight-type pipes(2) are held. The showcase comprises: 'Y'-shaped connecting members(6) formed developed in three directions while semi-circle connecting portions are kept at an obtuse angle; '<'-shaped connecting members(7) formed folded so that the semi-circle connecting portions form an obtuse angle in one direction.
