摘要： A hose includes an inner tube rubber layer, a woven material underlayer having a woven base material made of polyamide (PA) or polyethylene terephthalate (PET), and a reinforcing material layer, which are sequentially laminated on the inner rube rubber layer in this order. Following relationship formula (1) is to be satisfied, A ⋅ t + B ⋅ C D wherein "A" represents SO 4 2- concentration in the inner tube rubber layer (unit: mol/mm 3 ), "t" represents thickness of the inner tube rubber layer (unit: mm), "B" represents SO 4 2- concentration per 1 g of the woven base material (unit: mol/g), "C" represents mass of the woven base material per unit area of the woven material underlayer (unit: g/mm 2 ), and "D" represents a constant of 2.5 × 10 -9 (unit: mol/mm 2 ). 100 pbm of a rubber component contains at least 60 pbm of acrylonitrile butadiene rubber (NBR) and t ≥ 0.5 mm.
