To provide a front frame structure of an electric vehicle which can effectively protect a power unit and a control unit and a cabin and a battery chamber from an impact caused during a front collision.SOLUTION: A front frame structure includes: front side frames each having a wall-shaped part having a dimension in a height direction from a bottom part to an upper part of a motor room, and an arm-shaped part protruding from an upper part of a front end of the wall-shaped part; lower side frames each joined to a bottom part of the wall-shaped part and a front end of the arm-shaped part and forming an annular opening between itself and the arm-shaped part; and reinforcements each disposed in the opening. The reinforcement has a first diagonal member and a second diagonal member connected to each other and is jointed to the front end of the arm-shaped part, a rear end of the arm-shaped part, and a middle part of the lower side frame.SELECTED DRAWING: Figure 2
