An integrated circuit (100) in which a voltage divider circuit is integrated comprises a first resistor (121), second resistor (122), control portion (130), switch (140), and switching portion (150). The first resistor (121) and second resistor (122) form a resistive voltage divider element for dividing a voltage obtained by rectifying an alternating-current voltage, or a direct-current voltage, supplied to a control portion (130). The switch (140) is provided in series with the resistive voltage divider element, and passes or cuts off current passing through the resistive voltage divider element. The switching portion (150) switches the switch (140) so as to pass current during driving of the control portion (130), and cut off current during standby of the control portion (130). |
