Abstract
To provide a multilayered body with high adhesion between a resin layer containing a nanofiber or the like and a metal layer, and a method for manufacturing a multilayered body. The multilayered body contains: a metal layer having an uneven region with an average length (RSm) of a contour curve element from 0.5 to 10 μm; and a resin layer in contact with the uneven region of the metal layer, the resin layer containing a thermoplastic resin and a fibrous filler, the fibrous filler having a number average fiber diameter (F) of less than 1 μm, and a ratio (RSm/F) of the average length (RSm) of the contour curve element of the uneven region to the number average fiber diameter (F) from 1 to 20000.
