An adhesive-free flexible laminate formed from a polyimide film in which at least one surface has been plasma treated, a tie-coat layer formed on the surface of the plasma-treated polyimide film, a metal seed layer made of either copper or copper alloy and which is formed on the tie-coat layer, and a metal conductive layer made of either copper or copper alloy and which is formed on the metal seed layer, wherein the atomic percent of Cu inclusion in the tie-coat layer is 0.5 at % or less. Consequently, provided is a flexible laminate capable of effectively inhibiting the deterioration of the peel strength upon producing a flexible laminate (in particular a two-layer metalizing laminate).
