In order to provide an industrially washable waist support belt that strikes a balance between industrial washing durability and stretchability, a waist support belt according to the present invention comprises a belt-shaped body, the body comprising a base fabric, a male hook-and-loop fastener member, and female hook-and-loop fastener members. The male hook-and-loop fastener member is sewn to the base fabric at a first end of the body on a first side thereof. The female hook-and-loop fastener members are sewn to the base fabric at both ends of the body on a second side thereof. The male hook-and-loop fastener member contains 95% by mass or more of a polyester elastomer resin with respect to the mass of the male hook-and-loop fastener member. The female hook-and-loop fastener members contain 95% by mass or more of one or more type of resin selected from the group consisting of polyester resins and polyamide resins with respect to the mass of the female hook-and-loop fastener members. The base fabric is formed from one or more type of fibers selected from the group consisting of crimped polyester fibers and elastic polyurethane fibers. A first index [25% elongation stress (N/50 mm) of the base fabric/hysteresis loss (%)] × [shear stress (N) of the waist support belt] of the base fabric is 60–300.
