A cooking appliance comprising: a body that define a cooking chamber therein; a door rotatably connected to the body and configured to open and close at least a portion of the cooking chamber; a plurality of hinge mechanisms that roatably connect the door to the body; a control device disposed at the door; and a wire connected to the control device, wherein the door comprises a front panel having a rear surface that seats the control device, characterized in that the door further comprises: at least one intermediate panel that is spaced apart from the front panel, a rear panel spaced apart from the at least one intermediate panel and that is disposed rearward of the front panel toward the cooking chamber based on the door being closed, a pair of side frames (220, 221) that are positioned on both lateral sides of the at least one intermediate panel and that are disposed vertically below the control device based on the door being closed, at least one of the pair of side frames (220, 221) comprising a wire guide configured to guide the wire to the control device, and a lower frame configured to support the at least one intermediate panel and the rear panel, wherein the wire guide comprises: a first extension that contacts the rear surface of the front panel and that extends in a first direction from a first surface of the at least one of the pair of side frames (220, 221), a second extension that is bent from the first extension and that extends in a direction perpendicular to the rear surface of the front panel, and a third extension that is bent from the second extension and that extends toward the first surface of the at least one of the pair of side frames (220, 221) in a direction opposite to the first direction, and wherein the wire guide defines an accommodation space that is surrounded by the first, second, and third extensions (224a-c) and that is configured to accommodate the wire therein. a body that define a cooking chamber therein;
