Disclosed is a protector that lightens a shock when a wearer falls, and reduces an unpleasant feeling given to a wearer when worn for a long period of time. Protector 1 is substantially circular in a plan view and is disposed at a position to cover near a femoral-neck portion 21 from a side portion of a wearer. The protector 1 is curved in a thickness direction so that an outer surface 10, comprising a single-layer structure composed of a polymer-foam body, is convex, and an inner surface 20 is concave. An amount of displacement in the thickness direction when a load of 20 N is applied at a central portion of the outer surface 10 when placed on a flat surface is 3 mm - 20 mm.
