A composite electronic component may include a composite body including a capacitor and an inductor coupled to each other; an input terminal formed on a first end surface of the composite body and connected to the coil part of the inductor; an output terminal including a first output terminal formed on a second end surface of the composite body and connected to the coil part of the inductor and a second output terminal formed on the second end surface of the composite body and connected to the first internal electrode of the capacitor; and a ground terminal formed on a first end surface of the capacitor in the composite body. The capacitor may be coupled to a side surface of the inductor, and the sum of ratio of lengths of a short axis to a long axis of the coil part is 0.7 to 1.0.
