Abstract
A medical coil is provided which is formed by winding an element wire, and includes a convex part provided on a first end of a width direction of the element wire, and a concave part provided on a second end of the width direction of the element wire. At least one of the convex part and the concave part has a slant face. When a compressive force is applied in an axial direction of the medical coil, the convex part and the concave part adjacent to each other are configured to approach each other. A segment which connects a top part of the convex part which protrudes the most and a deepest part of the concave part which is deepest forms an angle so as not to be parallel to an axis of the medical coil.
