ABSTRACT:
In a method for producing a hose with a sealing layer, a hose body having a resin innermost layer is prepared, a rod-like core member is disposed through a center portion of a hollow interior of a connecting portion of the hose body so as to occupy the center portion, and the plasma gas is fed and distributed in an interior of an innermost layer of the connecting portion to modify an inner surface of the innermost layer. Then, the sealing layer is formed on the inner surface by coating an elastic material for the sealing layer on the inner surface of the connecting portion.
