A method of forming a laminated body by laminating a plurality of ceramics green sheets in a predetermined order, with a predetermined pattern printed thereon, said method comprising the steps of: forming a penetrating portion on a plurality of ceramics green sheets, and then: (a) forming a preceding lamination sheet which is treated as one ceramics green sheet by laminating and bonding at least two blank ceramics green sheets out of said plurality of ceramics green sheets; (b) screen printing a predetermined pattern on said preceding lamination sheet and a predetermined pattern on at least one non-preceding lamination sheet which is a ceramics green sheet not used for forming said preceding lamination sheet out of said plurality of ceramics green sheets; (c) laminating and bonding said preceding lamination sheet, comprising at least two ceramics green sheets out of said plurality of ceramics green sheets, and said non-preceding lamination sheet, which is a ceramics green sheet not used for forming said preceding lamination sheet out of said plurality of ceramics green sheets, on which said predetermined pattern is printed in said step (b), in a predetermined order; wherein each of the ceramics green sheets includes an oxygen ion conductive solid electrolyte (4, 6) as a ceramics component; and wherein the laminated body is a gas sensor element. forming a penetrating portion on a plurality of ceramics green sheets, and then: (a) forming a preceding lamination sheet which is treated as one ceramics green sheet by laminating and bonding at least two blank ceramics green sheets out of said plurality of ceramics green sheets; (b) screen printing a predetermined pattern on said preceding lamination sheet and a predetermined pattern on at least one non-preceding lamination sheet which is a ceramics green sheet not used for forming said preceding lamination sheet out of said plurality of ceramics green sheets; (c) laminating and bonding said preceding lamination sheet, comprising at least two ceramics green sheets out of said plurality of ceramics green sheets, and said non-preceding lamination sheet, which is a ceramics green sheet not used for forming said preceding lamination sheet out of said plurality of ceramics green sheets, on which said predetermined pattern is printed in said step (b), in a predetermined order; (a) forming a preceding lamination sheet which is treated as one ceramics green sheet by laminating and bonding at least two blank ceramics green sheets out of said plurality of ceramics green sheets; (b) screen printing a predetermined pattern on said preceding lamination sheet and a predetermined pattern on at least one non-preceding lamination sheet which is a ceramics green sheet not used for forming said preceding lamination sheet out of said plurality of ceramics green sheets; (c) laminating and bonding said preceding lamination sheet, comprising at least two ceramics green sheets out of said plurality of ceramics green sheets, and said non-preceding lamination sheet, which is a ceramics green sheet not used for forming said preceding lamination sheet out of said plurality of ceramics green sheets, on which said predetermined pattern is printed in said step (b), in a predetermined order; wherein each of the ceramics green sheets includes an oxygen ion conductive solid electrolyte (4, 6) as a ceramics component; and wherein the laminated body is a gas sensor element.
