A banknote bundling device (3) includes a bundling-side stacking unit (21) in which bundling-object-banknotes are sorted and stacked, a bundling unit (22) that bundles one hundred bundling-object-banknotes with a bundling tape, and a pre-bundling transport unit (25) and a hold and transport unit (27) that transports the bundling-object-banknotes stacked in the bundling-side stacking unit (21) to the bundling unit (22) when the number of the bundling-object-banknotes stacked in the bundling-side stacking unit (21) reaches one hundred. The banknote bundling device (3) further includes a banknote-kind acquisition unit (172) that acquires a banknote-kind of the last banknote stacked in the bundling-side stacking unit (21) from among the one hundred bundling-object-banknotes, and a bundling-position setting unit (174) that sets, based on the banknote-kind of the last banknote, a bundling position of the bundling tape on the bundling-object-banknotes. Consequently, the bundling position of the bundling tape can be set easily according to the banknote-kind.
