The fast electron spectrum was measured simultaneously with the proton energy in the interaction between the solid and the high intense laser. There were two components in the electron spectrum. The higher electron temperature component was almost explained by the ponderomotive formula. The total electron spectrum including the lower temperature component was also explained by a simple model. The detected maximum proton energy was 23 MeV with SUS thin foil target.
