A decorative sheet includes a decoration layer having air permeability and an adhesive layer on the decoration layer arranged to bond the decoration layer onto an object. The decoration layer has an adhesive permeated portion permeated with the adhesive that has diffused from the adhesive layer. The adhesive permeated portion is about one-fifth to about one-third as thick as the decoration layer. A method of making the decorative sheet includes providing the adhesive in a sheet shape, and forming an adhesive layer by applying the adhesive onto a decoration layer permeable to air. The step of forming the adhesive layer includes permeating a portion of the decoration layer with a portion of the adhesive, and making the adhesive permeate through a surface of the decoration layer to a depth corresponding to about one-fifth to about one-third of the overall thickness of the decoration layer.
