Formation of ethanol jet phenomena was observed with local contact microwave heating. The inverter-controlled magnetron makes the microwave. The jet heights and the jet shapes were measured with a high-speed video camera. A coaxial cable was used for the microwave transportation and for the heating. The microwave intensity (output power) was ranged from 20 W to 60 W. The exit diameter was from 1mm to 6mm. On the photographic observation, the jet shapes formed were classified into seven types. The pen type was observed with smaller exit diameter, and the arrowhead type was with larger microwave intensity. The spoon type, the fir-tree type, the mushroom type and the umbrella type were observed with larger exit diameter. The jet ratio was increased with the increase in the exit diameter and in the microwave intensity. In this research, the smallest droplets were formed in the explosion type. The explosion type ratio had the maximum at a certain exit diameter.
