A liquid ejecting apparatus capable of supplying liquid stably and continuously through a liquid supplying tube which performs a following deformation in accordance with a movement of a carriage embedded with a liquid ejecting head, while achieving compactness of a main body of the apparatus. By removing solvent molecules from the thin film until, effectively, none of the solvent molecules exist any longer in the atmosphere near the surface of the film while the atmosphere is at room temperature and a pressure 1 Pa or below, a thin film layer is formed from the solution including the film-forming component and the solvent. The top and bottom faces of the frames of the front meshed board and the rear meshed board are further provided with a plurality of insertion holes, whereby two such combinative pet cages can be connected vertically by the connecting parts.
