Abstract: A flexible member is provided which can have excellent load resistance and flexibility while being more compact. This flexible member has a main body part in which multiple wave washers having closed ring shapes is stacked in an axial direction and joined to each other by multiple joint parts, and the main body part is able to be bent with respect to the axial direction due to elastic deformation of the wave washers. Each of the joint parts includes: a pair of welded parts in linear shape, being gradually separated from each other in a circumferential direction from an inner circumferential side toward an outer circumferential side of the wave washer.
