A problem is to provide a sheet having a pre-sintering layer, the thickness of which following sintering is such as to be capable of relieving stresses. Solution means relate to a sheet comprising a pre-sintering layer. Viscosity at 90° C of the pre-sintering layer is not less than 0.27 MPa·s. Thickness of the pre-sintering layer is 30 µm to 200 µm. |
