Abstract
A wire for a medical device includes a wire body and a solid lubrication film. The wire body has an outer circumferential layer formed of a plurality of metal strands that are twisted with each other. The solid lubrication film is formed at least on outside exposed surfaces of the plurality of metal strands. When a virtual circle as a smallest circle enclosing the outer circumferential layer is assumed in a cross section perpendicular to a central axis of the wire body, a part of an outer edge of the solid lubrication film of the cross section is inside the virtual circle and a cross-sectional area of the solid lubrication film in the cross section satisfies A/B>0.7 where A is a size of a portion outside the virtual circle and B is a size of a portion inside the virtual circle.
