Claim:
1. A voltage smoothing circuit for smoothing a voltage, the circuit comprising: a multilayer capacitor which includes a first capacitance unit and a second capacitance unit; and a regulator which includes an input terminal and an output terminal, the input terminal being electrically connected to the second capacitance unit, the output terminal being electrically connected to the first capacitance unit; wherein the regulator calculates a first voltage which is applied to the first capacitance unit based on a second voltage which is applied to the input terminal and outputs the first voltage from the output terminal such that a potential difference which is applied to the first capacitance unit decreases when a potential difference which is applied to the second capacitance unit increases, and the potential difference which is applied to the first capacitance unit increases when the potential difference which is applied to the second capacitance unit decreases.
