Restoring force preserving portion-bonded medical tape and method for manufacturing the same

A method for manufacturing a medical tape, comprising:

• applying a solution polymer serving as an elastic base member portion having an elastic function to an upper layer of a restoring force preserving portion bent into a shape or shape having a projected cross-sectional shape by an external force and simultaneously performing a film formation of the elastic base member portion and a lamination of the restoring force preserving portion and the elastic base member portion to complete the film formation, obtaining the elastic base member portion, and obtaining a shaped or shaped two-layer structure having a projected cross-sectional shape, the two-layer structure being composed of the restoring force preserving portion and the elastic base member portion;
• and
• subsequently, removing the external force applied to the restoring force preserving portion to exert a restorability that the restoring force preserving portion has and obtaining a two-layer structure composed of the elastic base member portion and the restoring force preserving portion, the elastic base member portion being in a state where a residual shrink force generated in association with a forming shrinkage of the solution polymer is reduced by a restoring force associated with a shape change in a direction opposite to the residual shrink force generated in association with the forming shrinkage of the solution polymer.
