A method of manufacturing a terminal-equipped electric wire that includes an electric wire having a core wire made of a conductor and a covering portion made of an insulating material covering a periphery of the core wire, and a crimp terminal having: a base portion extending along an axial direction; a first barrel which extends from the base portion in an intersecting direction that intersects the axial direction, and is crimped in a state of surrounding an outer circumference of a core wire exposed portion in which an outer peripheral surface of the core wire in the electric wire located between the first barrel and the base portion is exposed to the outside; a second barrel which extends from the base portion in the intersecting direction, is located on a rear side of the first barrel in the axial direction, and is crimped in a state of surrounding an outer circumference of the covering portion of the electric wire; and an opening portion in which the core wire exposed portion and the covering portion are exposed to an outside between the first barrel and the second barrel, the method comprising: a peeling step of peeling the covering portion of the electric wire to form a core wire exposed portion (21 A); characterized in an adhesive member pasting step of pasting an adhesive member having a base member and adhesive layers (42, 43) formed on both sides of the base member to the covering portion of the electric wire such that the adhesive layer wraps a whole circumference of the covering portion; wherein an inner adhesive layer adheres to the outer circumference of the covering portion, and an outer adhesive layer for adhering to an inner circumference of the second barrel, the inner adhesive layer and the outer adhesive layer are made of an acrylic or polyester-based material having elasticity, a placing step of placing the electric wire with respect to the crimp terminal before crimping such that the second barrel and the adhesive member overlap; a crimping step of crimping the electric wire and the crimp terminal before crimping; and an anticorrosive portion forming step of applying an anticorrosive agent to at least the opening portion and curing the anticorrosive agent to form an anticorrosive portion. a peeling step of peeling the covering portion of the electric wire to form a core wire exposed portion (21 A); characterized in an adhesive member pasting step of pasting an adhesive member having a base member and adhesive layers (42, 43) formed on both sides of the base member to the covering portion of the electric wire such that the adhesive layer wraps a whole circumference of the covering portion; wherein an inner adhesive layer adheres to the outer circumference of the covering portion, and an outer adhesive layer for adhering to an inner circumference of the second barrel, the inner adhesive layer and the outer adhesive layer are made of an acrylic or polyester-based material having elasticity, a placing step of placing the electric wire with respect to the crimp terminal before crimping such that the second barrel and the adhesive member overlap; a crimping step of crimping the electric wire and the crimp terminal before crimping; and an anticorrosive portion forming step of applying an anticorrosive agent to at least the opening portion and curing the anticorrosive agent to form an anticorrosive portion.
