PROBLEM TO BE SOLVED: To provide a superconductive critical current measuring instrument which can stably perform measurement without being affected by the occurrence of icing when measuring the superconductive critical current of a membrane superconductive wire. SOLUTION: The superconductive critical current measuring instrument includes means for avoiding that the contact of a measuring electrode and a wire material to be measured becomes impossible by icing. A first means is constituted by forming the peripheral part of at least the contact part with the wire material to be measured of a receiving stand from a material hard to cause icing. A second means is constituted by setting the width dimension of the contact part with the wire material to be measured of the receiving stand to a range of 50-100% of the width dimension of the wire material to be measured and making the position of the non-contact part with the wire material to be measured lower than the contact part. A third means is constituted by setting the width dimension of the measuring electrode to a range of 50-100% of the width dimension of the wire material to be measured.
