The present invention provides a flexible tube used for an endoscope and the like； an endoscopic medical apparatus that uses the flexible tube； and a resin composition for top coat layer used for the flexible tube. The flexible tube includes a flexible tube substrate that has a cylindrical shape and flexibility； a resin layer that covers the flexible tube substrate； and a top coat layer that covers the resin layer, in which the top coat layer contains a polymer compound derived from monomers including the following A to C.[A: hydroxyl group-free acrylate having a100 parts by mass]molecular weight equal to or greater than 110[B: hydroxyl group-free acrylate having a10 parts by mass tomolecular weight equal to or greater than 80 and200 parts by mass]less than 110[C: hydroxyalkyl acrylate1 part by mass to60 parts by mass]
