In a coextrusion molding method, a laminate having excellent interlaminar adhesion strength with a fluorocopolymer is provided, and also a laminate which can be used more than enough even at high temperatures or in applications where the laminate comes into contact with oil, gasoline or the like by controlling various properties of the adhesive layer is provided. The laminate of the present invention is a laminate of at least two or more layers comprising a structure obtained by bonding and laminating an adhesive (A) defined by the following (i) to (iii) and a fluorocopolymer (B), wherein the adhesive (A) (i) is obtained by allowing a polyolefin (a) having a group reactive with a carbodiimide group to react with a compound (b) having a carbodiimide group, (ii) has a ratio of peak intensity at 2130 to 2140 cm -1 to peak intensity at 1470 cm -1 of 60% or lower in infrared absorption spectroscopy, and (iii) has a density of 0.870 to 0.940 g/cm 3 . In the formula (1), R 1 and R 2 each independently represent a hydrogen atom or fluorine atom. In the formula (2), R 3 represents a substituent represented by C n H 2n+1 ( in which n is an integer of 1 or more).
