1. An electric circuit comprising:
a first power-supply line;
a second power-supply line;
a ground line;
a first circuit including a first capacitance component having a first capacitance, the first circuit being configured to be electrically connected to the first power-supply line via a first power-supply terminal and electrically connected to the ground line via a first ground terminal;
a second circuit including a second capacitance component having a second capacitance smaller than the first capacitance, the second circuit being configured to be electrically connected to the second power-supply line via a second power-supply terminal and electrically connected to the ground line via a second ground terminal;
an RC series circuit disposed between the first power-supply terminal and the first ground terminal;
a capacitor disposed between the second power-supply terminal and the second ground terminal; and
a noise filter disposed between the first power-supply line and the second power-supply line.
