Growth phenomena of viscous finger in a square Hele-Shaw cell were examined. Surfactant solution was used as a high viscous fluid and air was used as a low viscous fluid. Pressurized air was injected from an inlet located in the center of downside of the Hele-Shaw cell filled with a surfactant solution and viscous fingers radiated out from the inlet. Three main growth patterns were observed, which depends on differences in concentration of sample fluids, injection pressure and channel size. Change of pattern during the finger growth and relation between these patterns and growth speed were examined. In addition, characteristic phenomena such as jumping of finger's tip and smaller splittings on side of straight finger were observed.
