Disclosed are: a structural member for use in an eyeglass which has a super elastic property and shape memory property while retaining an excellent biocompatibility in addition to the fact that it is N-free, and which also has an excellent cold workability; an eyeglass frame containing the structural member; and a process for producing the structural member or eyeglass frame. A structural member for an eyeglass containing a Ti—Nb—Zr alloy which comprises (A) 40 to 75% by weight of Ti, (B) 18 to 30% by weight of Nb, (C) 10 to 30% by weight of Zr and (D) 0.2 to 3.7% by weight of at least one additive metal element selected from the group consisting of Al, In and Ga.
