To improve a designability of a decorative sheet attached to an adherend having a three-dimensional shape.SOLUTION: An attaching method of a decorative sheet 20 includes a molding step of pre-molding the decorative sheet 20 by using a jig 30, and an attaching step of attaching the pre-molded decorative sheet 20 to an adherend AB. The jig 30 includes a first bending part 41 and a second bending part 42 that extends in a direction non-parallel to the direction in which the first bending part 41 extends. In the molding step, the decorative sheet 20 is molded so as to include: a base part 25 extending over a base surface 40 defined by the first bending part 41 and the second bending part 42 by pulling the decorative sheet 20 and bending it at the first bending part 41 and the second bending part 42; a first side part 26 that is connected to the base part 25 at the first bending part 41 and is bent relative to the base part 25 at the first bending part 41; and a second side part 27 that is connected to the base part 25 at a second bending part 42 and is bent relative to the base part 25 at the second bending part 42.SELECTED DRAWING: Figure 1

    【課題】三次元形状の被着体に貼り付けられる加飾シートの意匠性を改善する。【解決手段】加飾シート20の貼付方法は、治具30を用いて加飾シート20を予備成形する成形工程と、予備成形された加飾シート20を被着体ABに貼り付ける貼付工程と、を含む。治具30は、第1曲部41と、第1曲部41が延びる方向とは非平行な方向に延びる第2曲部42と、を含む。成形工程において、加飾シート20を引っ張り、且つ第1曲部41及び第2曲部42において曲げることによって、第1曲部41及び第2曲部42によって規定されるベース面40上に広がるベース部25と、第1曲部41上においてベース部25と接続し第1曲部41上でベース部25に対して曲げられている第1側部26と、第2曲部42上においてベース部25と接続し第2曲部42上でベース部25に対して曲げられている第2側部27と、を含むように加飾シート20を成形する。【選択図】図1
