Provided is a layered product with high jet-black. A layered product according to the present invention is a layered product (10) including at least a first layer (1) and a second layer (2) that are stacked. A value of L* in a L*a*b* color system defined by JIS Z8729 of the first layer (1) is ten or less. The second layer (2) is formed on the first layer (1) and 0.1 to 1 mass % of carbon nanotubes are contained in a material constituting the second layer (2). In the L*a*b* color system defined by JIS Z8729, when values are measured from a side of a plane of the second layer (2), a value of L* is 2.5 or less, a value of a* is −2.0 or greater and 2.0 or less, and a value of b* is −2.0 or greater and 0.5 or less.
