Abstract
An irrigation hose (10) includes a continuous strip member (27). The continuous strip member (27) is formed by extruding a substrate (20) and allowing the substrate (20) to cool. Then a flow path (25) is extruded on the substrate (20). The continuous strip member (27) is then operatively connected to the inner wall 10a of the irrigation hose (10).
