PROBLEM TO BE SOLVED: To provide, at a low cost, a curvy strengthened glass.SOLUTION: The provided method for manufacturing a curvy strengthened glass 1 includes a joining step of forming a glass sheet laminate 6 by laminating and mutually joining multiple glass sheets 4 and 5 and a strengthening step of chemically strengthening the glass sheet laminate 6 based on the ion exchange method. The respective chemically strengthened characteristics of the glass sheets 4 and 5 are different. For this reason, a dimensional variation difference arises in-between the glass sheet 4 and glass sheet 5 due to ion exchange of the strengthening step, resulting in the curvature of the glass sheet laminate 6. |
