PROBLEM TO BE SOLVED: To provide a decoration sheet for the game machines which achieves a higher decomposition rate by effectively utilizing botanical wastes and surplus plants. SOLUTION: A transparent film 1 making up the decoration sheet is produced using a biodegradable resin. A picture pattern printed layer 2 is printed with a biodegradable ink. The biodegradable resin can use a completely decomposable type biodegradable resin produced using the botanical wastes such as mechanical wastes of the pachinko game machines as material. It is also possible to use a decayable type biodegradable resin mixed with the botanical natural polymer extracted from the surplus plants for the live stock feed, etc. as the general-purpose synthetic resin such as polyethylene.
