抄録	Zirconium-based metallic glass was anodically-bonded to soda-lime glass as a trial. Faying surfaces of the joint pieces were finished by buffing and bonded in a pure argon atmosphere with a bonding voltage of 500 V. At a bonding temperature of 473 K intimate contact all over the joint interface was achieved with a bonding time of 7200 s. The bonding process was accelerated with increase of the bonding temperature. The obtained bond interfaces were strong, but cracks occurred in the soda-lime glass due to the residual stress caused by the difference in expansion coefficients of the metallic glass and the soda-lime glass. By transmission electron microscopy, it was found that the metallic glass kept its amorphous nature through the anodic bonding process. An oxidation layer ～100 nm thick was found at the bond interface. The oxidation layer was composed of a crystalline sublayer contacting to the metallic glass and an amorphous sublayer contacting to the soda-lime glass.
