Abstract
A production method for a shaped object includes preparing a formable resin sheet that includes a base made from a resin, and a thermally expansive layer provided on a first side of the base and containing a thermally expandable material, a thermal conversion layer forming step of forming a thermal conversion layer that contains an electromagnetic wave heat conversion material that converts electromagnetic waves to heat on a first side of the formable resin sheet, an electrically conductive layer forming step of forming an electrically conductive layer on a second side of the formable resin sheet, and an irradiating step of, after forming the thermal conversion layer and the electrically conductive layer, irradiating the thermal conversion layer with the electromagnetic waves to cause the thermal expansive layer to distend and cause the base to deform in accordance with the distension of the thermal expansive layer. The thermal conversion layer and the electrically conductive layer are formed such that at least a portion of the electrically conductive layer is opposite at least a portion of the thermal conversion layer, with the base and the thermally expansive layer interposed therebetween.
