Claim 0:
1. A laminate having two or more layers comprising Layer (a) and Layer (b),
the Layer (a) contains an aliphatic polyamide composition (A),
the Layer (b) contains a modified polyolefin (B),
the modified polyolefin (B) is a maleic anhydride-modified polpropylene,
the modified polyolefin (B) has a Shore hardness (D scale) measured in accordance with ASTM D2240 of 30 or more and 61 or less,
the aliphatic polyamide composition (A) contains a polyamide (A1), an impact resistant agent and a plasticizer,
the polyamide (A1) is polyamide 11, polyamide 12, or polyamide 610,
the impact resistant agent is an elastomer polymer which has a constitutional unit derived from an unsaturated compound having a carboxyl group and/or an acid anhydride group, and has a Shore hardness (D scale) measured in accordance with ASTM D2240 of less than 30, and a content of the impact resistant agent in the aliphatic polyamide composition (A) is 5% by mass or more and 30% by mass or less based on 100% by mass of the aliphatic polyamide composition (A),
a content of the plasticizer in the aliphatic polyamide composition (A) is 1% by mass or more and 10% by mass or less based on 100% by mass of the aliphatic polyamide composition (A),
a thickness of Layer (a) in the laminate is 50% or more and 95% or less based on the total wall thickness of the laminate,
a thickness of Laver (b) in the laminate is 5% or more and 50% or less based on the total wall thickness of the laminate, and
the total wall thickness of the laminate is 0.5 mm or more and 25 mm or less.
