Provided is a hand joint supporter which can reduce the load on the hand joints and prevent hand tenosynovitis. The hand joint supporter (10) comprises a first anchor section (2) for tightening the wearer's forearm with a tubular knitted fabric, a second anchor section (3) for tightening the palm and back of the wearer's hand with the tubular knitted fabric, a hole anchor section (11) being formed as a roughly circular through-hole in the vicinity of the second anchor section (3) in the tubular knitted fabric to insert the wearer's thumb therethrough, and a supporting section (4) extending in the front side and/or back side of the tubular knitted fabric, along the lengthwise direction of the tubular knitted fabric, across the part covering the caprometacarpal joint and being joined to the first anchor section (2) and the hole anchor section (11) so as to support the wearer's hand joints, wherein the stretch resistance, in the circumferential direction of the tubular knitted fabric, of the first anchor part (2) is larger than the stretch resistance, in the circumferential direction of the tubular knitted fabric, of a base fabric section (1), and the stretch resistance, in the length width direction of the tubular knitted fabric, of the supporting section (4) is larger than the the stretch resistance, in the length width direction of the tubular knitted fabric, of the base fabric section (1).本發明在於提供一種可減少對手關節之負擔並防止手之腱鞘炎的手關節支撐帶。手關節支撐帶10具備：第1固著部2，其使筒狀織物緊固於前臂；第2固著部3，其使筒狀織物緊固於手心及手背；孔固著部11，其於筒狀織物中第2固著部3附近由大致圓形形狀之貫通孔所形成，且供手之第1指插通；及支撐部4，其於筒狀織物之正面及/或背面側，橫跨腕掌關節所對應之部分，並於筒狀織物之長度方向延伸而編成，且連結於第1固著部2及孔固著部11而支撐手關節；筒狀織物之圓周方向上之第1固著部2之伸縮阻力，大於筒狀織物之圓周方向上之基底布料部1之伸縮阻力，筒狀織物之長度方向上之支撐部4之伸縮阻力，大於筒狀織物之長度方向上之基底布料部1之伸縮阻力。
