Abstract
An insert according to the invention includes a needle tube that has an inclined surface having a leading end opening, a needle base that has a chamber communicating with an inside of the needle tube and holds the needle tube, and a light introduction portion that communicates with the chamber and has an insertion path into which a light guide member is inserted. In a case in which the light guide member is inserted into the insertion path, is constrained at a first constraint point, becomes free, is bent, is constrained at a second constraint point, and is inserted into the needle tube and a point where an extension line in an insertion direction of the light guide member in the vicinity of a chamber-side opening in the insertion path intersects a line which passes through the second constraint point and is parallel to an axial direction of the needle tube is an intersection point, a distance between the intersection point and the second constraint point is longer than a distance between the first constraint point and the intersection point.
