To provide a thermosensible adhesive paper for a three-dimensional shaping machine of which the paper has a preferable thermosensibility to use for a three-dimensional shaping machine of a thermal adhesion type and can give a high dimensional accuracy by effectively suppressing the extension and shrinkage of a shaped item caused by its absorbing and releas ing water from air.

The thermosensible adhesive paper is used in a three-dimensional shaping machine to prepare a three-dimensional shaping item, in which machine a thrmosensible adhesive paper (31) having a thermosensible adhesive layer on its lower side is provided continuously onto the upper surface of a stage (32) which is movable upward and downward, the thermosensible adhesive paper is adhered to a surface of the stage or another sheet of thermosensible adhesive paper already provided by heating and pressurizing the surface, a laminated item (44) having two or more layer is formed by drawing cutting lines (41, 42, and 43) on the thermosensible adhesive paper and unnecessary portions are cut off from the laminated item. For the thermosensible adhesive paper, 5-30 g/m2 of a thermosensible adhesive layer whose melting point is 50-150°C is laminated on the side of a base paper of 40-200 g/m2 of a weight per unit area. The base paper has a cellulose fiber as its main component and contains 5-60 wt% of a thermal adhesive binder material.
