PURPOSE: To produce easily a chain for ornamentation which is excellent in design using a composite material constituted by joining plural pieces of long- sized members made of a noble metal with a spacer metal therebetween to manufacture the chain then dissolving the spacer metal with a chemical treating liquid.

CONSTITUTION: The spacer metal 4 which is dissolved by the chemical treating liquid is joined at joint surfaces 5, 6 by brazing or welding between strips 3A and 3B made of the noble metal as the long-sized members made of the noble metal to manufacture a piece is cut to a specified length and the cut members are successively intersected while links are formed. The chain is braided by inside and outside noble metal rings 3a, 3b joined at a joint 2 and the links 3' consisting of the spacer metal 4. The resulted chain is dipped into the chemical treating liquid to dissolve away the metal 4. The chain intersected with the annular link 3 consisting of the two noble metal rings 3a, 3b on the inside and outside is completed by such treatment.
