<p>Provided is an LC composite electronic part exhibiting a large noise suppression effect without increasing the part size. The LC composite electronic part is formed by layering a first and a second capacitor (10, 20) and a first and a second coil (30, 40). The LC composite electronic part has four sets of LC resonance circuits. A noise circulation capacity (C21) is formed between a coil electrode (31a) and a resonance adjustment electrode (51a). A noise circulation capacity (C22) is formed between the coil electrode (31c) and the resonance adjustment electrode (51b). A noise circulation capacity (C23) is formed between a coil electrode (42a) and a resonance adjustment electrode (53a). A noise circulation electrode (C24) is formed between a coil electrode (42c) and a resonance adjustment electrode (53b). A noise circulation electrode (C25) is formed between pull-out electrodes (32b, 41b). A noise circulation electrode (C26) is formed between pull-out electrodes (32d, 41d).</p>
