Abstract
Abstract A shape memory alloy is used for face-contacting parts (1, 3, 4, 5; 101) and lens-fixing parts (2) of a spectacle frame, and parts (12, 13; 103) connected thereto are formed of titanium, a titanium alloy, nickel, or a chromium alloy. These parts are suitable soldered by a soldering material (111) formed of 5-15 wt. % of palladium, 5-15 wt. % of gallium, and a balance consisting of silver.
