Provided is a binding apparatus with which the quality of an object to be bound can be ensured and the burden on an operator can be reduced. A binding apparatus includes a pressure bonding mechanism in which pressure is applied by a pair of pressure bonding plates 34 and 35 to a joining portion of a binding tape 8, which is an adhesive tape, to fasten it together by gripping and squeezing a pair of levers 2 and 3 to rotate a pair of arms 4 and 5 around a fulcrum 6. Thereby, any mixing of metal staples into an object to be bound as in a conventional binding apparatus is eliminated, and thus the quality of the object to be bound can be ensured. Further, the need for a strong grip strength like that when ejecting a staple is eliminated, and thus the burden on an operator can be reduced.
