Laminate, method of manufacturing laminate, and method of manufacturing optical member

A method of manufacturing a laminate, the method comprising:

• a step of cutting a laminated sheet including a first member, a second member, and a third member in this order with a laser to obtain a laminate comprising, in the following order:
• the first member;
• the second member;
• and the third member,
• wherein an adhesion strength in a contact surface between the first member and the second member is represented by C1, an adhesion strength in a center portion of a contact surface between the second member and the third member is represented by C21, and an adhesion strength in at least a part of an outer peripheral portion positioned outside the center portion of the contact surface between the second member and the third member is represented by C22, a requirement of Expression (1) is satisfied,
• C22>C1>C21, Expression (1)
• the first member includes a first protective film and a pressure-sensitive adhesive layer,
• the second member includes a substrate and a liquid crystal layer, the third member includes a second protective film,
• the pressure-sensitive adhesive in the first member layer faces towards the second member, and
• the liquid crystal layer in the second member faces towards the third member;
• wherein in the laminated sheet, an adhesion strength in a contact surface between the first member and the second member is represented by C1 and an adhesion strength in a contact surface between the second member and the third member is represented by C2, a relationship of Expression (2) is satisfied,
• C1>C2. Expression (2)
