Fluororesin, laminate, tube, and tube manufacturing method

A laminate comprising:

• a fluororesin layer/a first polyamide resin layer/an ethylene/vinyl alcohol copolymer (EVOH) layer/a second polyamide resin layer/a third polyamide resin layer as an innermost layer/an inner layer/an intermediate layer/an outer layer/an outermost layer, the fluororesin having a reactive functional group, wherein a difference between a loss elastic modulus at 270° C. of the fluororesin (G″270) and a loss elastic modulus at 280° C. of the fluororesin (G″280) (G″270-G″280) is 2,500 Pa or more,
• the first polyamide resin layer, the second polyamide layer, and the third polyamide layer each independently containing a polyamide resin,
• one or both of the first polyamide resin layer and the second polyamide layer being polyamide 612,
• the EVOH layer containing an EVOH resin,
• wherein the fluororesin layer and the first polyamide resin layer are directly adhered to each other,
• the first polyamide resin layer and the EVOH layer are directly adhered to each other,
• a thickness of the fluororesin layer, which is the innermost layer, is 0.01 to 0.5 mm,
• a thickness of the first polyamide layer, which is the inner layer, is 0.01 to 1.0 mm,
• a thickness of the EVOH layer, which is the intermediate layer, is 0.01 to 0.5 mm,
• a thickness of the second polyamide layer, which is the outer layer, is 0.01 to 1.0 mm, and
• a thickness of the third polyamide layer, which is the outermost layer, is 0.01 to 1.0 mm.
