A hand joint supporter which can reduce the load on hand joints includes a first anchor section for tightening the wearer's forearm with a tubular knitted fabric, a second anchor section for tightening the palm and back of the wearer's hand with the fabric and a hole anchor section formed as a roughly circular through-hole in the vicinity of the second anchor section. A supporting section extends lengthwise in the fabric across the part covering the caprometacarpal joint and is joined to the first anchor section and the hole anchor section so as to support the wearer's hand joints. Stretch resistance, in the circumferential direction of the fabric of the first anchor part is larger than that of a base fabric section, and stretch resistance, in the length width direction of the fabric, of the supporting section is larger than that of the base fabric section.
