It is an object of the invention to provide a carbodiimide modified polyolefin adhesive having excellent adhesive strength in a room temperature atmosphere and excellent adhesive strength in a high temperature atmosphere even in continuously molding with a practical molding machine. An adhesive (D), i.e., a carbodiimide modified polyolefin adhesive of the present invention which can solve the above problem is obtainable by allowing a polyolefin (A) having a group capable of reacting with a carbodiimide group to react with a carbodiimide group-containing compound (B) in the presence of an unmodified polyolefin (C) and having a ratio of a peak intensity at 2130 to 2140 cmto a peak intensity at 1470 cm, as determined by infrared absorbance analysis, of not more than 60% and a density of 0.870 g/cmto 0.920 g/cm. Furthermore, the use of the adhesive provides a laminate of a polar resin (F) and a polyolefin (G) having excellent interlaminar adhesive force both under a room temperature atmosphere and under a high temperature atmosphere.
