A multilayer array electronic component includes a multilayer composite including a helical coil and a capacitor that are defined by stacking a coil conductor, a capacitor conductor, and a ceramic sheet on one another. External electrodes are arranged on the surface of the multilayer composite and electrically connected to the helical coil or the capacitor. A direction identification mark is arranged on the upper surface of the multilayer composite and electrically connected to any of the external electrodes through the helical coil or the capacitor.
