Abstract

A gravure printing device includes a substrate stage (11) on which a substrate (2) is fixed, an intaglio plate (21) for holding conductive paste, and a control device (7) for controlling a series of printing operations including a supply operation of supplying conductive paste (3) to a printing pattern of the intaglio plate (21) and a transfer operation of transferring the conductive paste (3) to the substrate (2). The control device (7) repeatedly performs the series of printing operations a plurality of times with respect to the identical printing position on the substrate (2). A printing pattern laminate made of the conductive paste laminated into the shape of the printing pattern is formed on the substrate (2). This makes it possible to form lines and bumps on a substrate made of a heat-sensitive material, while preventing the occurrence of metamorphosis of the substrate made of the heat-sensitive material.
