Beschreibung
Zusammenfassung:	Provided are a flexible tube for an endoscope, the flexible tube having good elasticity, being capable of sufficiently maintaining adhesiveness between a flexible-tube base and a polymer cover layer covering the flexible-tube base even when a bending operation is repeated, and being less likely to undergo a decrease in elasticity even when the flexible tube is repeatedly heated, an endoscopic medical device including the flexible tube for an endoscope, and methods for producing the flexible tube and the endoscopic medical device.The flexible tube for an endoscope has a flexible-tube base containing metal as a constituent material, a porous layer on the flexible-tube base, a primer layer on the porous layer, and a polymer cover layer on the primer layer. The polymer cover layer includes at least one compound of a polyamide, a polyester, a polyurethane, or a polyolefin on a side in contact with the primer layer.
