摘要:
A spectacle frame comprises a face-contacting portion such as a side and a lens-fixing portion such as a rim, both the portions being made of a shape memory alloy, and connecting members to be connected with the face-contacting portion and the lens-fixing portion. The connecting member is made of a titanium alloy, preferably .beta.-phase. The face-contacting portion and the lens-fixing portion are soldered to the connecting member with a palladium-based soldering material.
