Embodiment 1
[0222] [Production of functional sheet 101]
[0223] The functional sheet shown in Fig. 1(A) was produced in the following steps.
[0224] Using biaxially stretched polypropylene (Oji F-Tex Co., Ltd. E-201F, thickness 50 μm (in Table 1, PP)) as the first release film, the infrared shielding layer coating composition was prepared according to the following formulation , using a dispensing coater for coating. For coating, the layer thickness was adjusted so that the optical density was 0.12 and the coating was performed. The layer thickness was adjusted so that the dry layer thickness was 3.0 μm, and the coating was performed.

Embodiment 2
[0293] [Production of functional sheet 201]
[0294] In preparation of the functional sheet 102, the functional sheet 201 of the comparative example was produced in the same manner except that the second release film was not laminated.
[0295] [Production of functional sheet 202]
[0296] In the production of the functional sheet 102, the aging temperature was adjusted, and the peeling force of the first release film and the second release film were both adjusted to 70mN / 50mm. In addition, the functional sheet of the comparative example was produced in the same manner. 202.
[0297] [Production of functional sheet 203]
[0298] In the production of the functional sheet 102, the aging temperature was adjusted, and the peeling force of the first release film and the second release film were both adjusted to 2400mN / 50mm. In addition, the functional sheet of the comparative example was produced in the same manner. 203.
