In a radio-controlled timepiece, a tuning unit outputs a signal corresponding to a radio signal. An amplifier unit amplifies a signal output from the tuning unit. A receiving unit that extracts the time code from the amplified signal has a filter unit that selectively allows one of frequency signals to pass therethrough. A time-correcting unit acquires current time information from the extracted time code to correct a current time clocked by a clock unit. A control unit detects a voltage level of a signal output from the amplifier unit at two or more points while changing a capacitance value of a variable-capacitance unit of the tuning unit, uses, as a tuning point, a point meeting a given requirement among the points where the voltage level has been detected, and sets the capacitance value of the variable-capacitance unit at the tuning point as a capacitance value to receive the time code when it is judged that a time code has been output from the receiving unit at the tuning point. When it is judged that no time code is output from the receiving unit at the tuning point, the control unit controls the filter unit so as to change the frequency that the filter unit allows a signal to pass therethrough.
