The effect of laser incidence angle on the angular distribution of hot electrons generated in the interaction of an ultrashort intense laser pulse with the foil target are investigated. A new emission peaked in the target surface direction is observed for the first time. With the increase of the incidence angle, the ratio of the number of surface electrons to the total electron number increases, while the number of transmitted electron through the target decreases. It is believed that the surface hot electrons are caused by the confinement of the quasi-static surface magnetic field and electric field.
