PROBLEM TO BE SOLVED: To provide a fluororesin laminate having non-adhesiveness, corrosion resistance and steam resistance of the fluororesin laminate, suppressing lowering of the friction abrasion resistance by preventing separation of a hard filler while keeping adhesiveness to a metal base material, and having inexpensive and higher friction abrasion resistance. SOLUTION: The fluororesin laminate is composed of at least three layers of a primer layer formed on the base material, an intermediate layer formed on the primer layer, and a top coat layer formed on the intermediate layer. The intermediate layer and top coat layer contain the hard filler with at least one kind of new Mohs hardness of 10 or more, respectively, and any hard filler contained in the top coat layer preferably has an average particle size smaller than that of any hard filler contained in the intermediate layer.
