and a plurality of portions for sticking to a side surface of the teat and extending outwards from a portion for sticking to the teat opening; the portion for sticking to the teat opening being exposed to an exterior at a plurality of places interposing at least the vertical line or the transverse line among them. ### Claim 6 (depends on 5) The method of protecting the teat opening of livestock according to claim 5, wherein said laminate has a planar shape without any corner portion where straight lines intersect each other. ### Claim 7 (depends on 6) The method of protecting the teat opening of livestock according to claim 6, wherein a diameter of the circular planar shape or a long axis of the elliptic planar shape forming the portion for sticking to the teat opening, has a length of 5 to 40 mm. ### Claim 8 (depends on 5) The method of protecting the teat opening of livestock according to claim 5, wherein the portion for sticking to the side surface of the teat have a shape expanding outwards. ### Claim 9 (depends on 5) The method of protecting the teat opening of livestock according to claim 5, wherein when a rectangular virtual circumscribing quadrilateral is formed on the planar shape of said laminate, a long side of said circumscribing quadrilateral has a length in a range of 30 to 200 mm while a short side thereof has a length in a range of 20 to 150 mm. ### Claim 10 (depends on 1, 2) The method of protecting the teat opening of livestock according to claim 1 or 2, wherein a removable protection film is laminated on the surface of said laminate on the side opposite to the adhesive layer, and a parting sheet is stuck to the surface of said adhesive layer. ### Claim 11 (depends on 1, 2) The method of protecting the teat opening of livestock according to claim 1 or 2, wherein said elastic sheet is formed of polyurethane. ### Claim 12 (depends on 1, 2) The method of protecting the teat opening of livestock according to claim 1 or 2, wherein said elastic sheet is colored.
