1. An electric range, comprising:
a case;
a cover plate coupled to an upper end of the case, wherein an object to be heated is placed on an upper surface thereof;
an air blowing fan configured to discharge air; and
an air guide that communicates with the air blowing fan, wherein a cross-sectional area of the flow path of air in a portion of the air guide at which air is discharged outward is greater than a cross-sectional area of the flow path of air at a portion of the air guide at which the air guide and the air blowing fan communicate, wherein the air guide comprises:
a first area that communicates with the air blowing fan and guides air to flow;
a second area that guides the air to be discharged outward; and
a changing area that connects the first area and the second area and changes a flow direction of air having passed through the first area to the second area, and wherein the cross-sectional area of the air guide increases gradually from the first area to the changing area, and the second area.
