The interfacial tension gradient originating from a temperature gradient causes particle migration. Previously, the authors reported the manipulation of a metal sphere in a glass using a near-infrared (NIR) laser. The NIR laser beam was not absorbed by the glass but by the metal sphere, causing the metal sphere to heat up. The local softening of the surrounding glass enabled metal sphere migration. The driving force was explained in terms of an interfacial gradient induced by the temperature distribution. In this study, metal sphere migration driven by surface heating was investigated. A metal sphere located near a surface migrated toward the surface owing to surface heating using a CO2laser and finally exited the glass. This phenomenon was observed using a charge-coupled device camera. A numerical calculation showed that the temperature at the metal sphere was 2760 K, and the temperature difference between the illuminated and non-illuminated metal sphere surfaces was 70 K. The driving force was calculated as 73 nN. The results confirmed that the glass surface heating caused the temperature distribution and the metal sphere migration.
