Composite electronic component and board having the same

A composite electronic component comprising:

• a composite body in which a capacitor and an electrostatic discharge (ESD) protection device are coupled to each other,
• the capacitor including a body in which a plurality of dielectric layers and internal electrodes facing each other, with the dielectric layers interposed therebetween, are stacked, and
• the ESD protection device including first and second lead electrodes disposed on the body of the capacitor, a discharge part disposed between the first and second lead electrodes, and a protection layer disposed on the first and second lead electrodes and the discharge part;
• an input terminal connected to the internal electrodes of the capacitor and the first lead electrode of the ESD protection device;
• and
• a ground terminal connected to the internal electrodes of the capacitor and the second lead electrode of the ESD protection device,
• wherein G2/G1<4.0, in which G1 is a distance, in a stacking direction of the internal electrodes, between the internal electrodes adjacent to each other and G2 is a distance, in a direction perpendicular to the stacking direction, between the first and second lead electrodes.
