This inkjet printing device comprises a conveyance path by which a sheet to be assembled as a corrugated cardboard box having a plurality of walls is conveyed in a conveyance direction, and inkjet heads that are positioned facing the surface of the sheet in the conveyance path and that can print a printed pattern in predetermined print ranges of an intersecting direction that intersects the conveyance direction along the surface of the sheet. The inkjet heads are positioned so that the print ranges span between first regions, which are intended to be first walls when the sheet is assembled into a corrugated cardboard box, and second regions, which are adjacent to the first regions in the intersecting direction and are intended to be second walls separate from the first walls.
