<P>PROBLEM TO BE SOLVED: To provide a compact and highly stable oscillator which easily corrects a frequency shift caused by a temperature fluctuation. Ž<P>SOLUTION: The oscillator includes: an overtone crystal vibrator 11 of three or higher dimension; an oscillation circuit 12 which is connected to the crystal vibrator 11 and outputs an oscillation frequency; a divider 13 which divides the oscillation frequency and outputs the divided frequencies to a system device processing unit 2; a temperature sensor 16 which detects a temperature around the crystal vibrator 11; and a memory 17 which stores information for correcting a frequency shift of an oscillation frequency according to the temperature characteristic of the crystal vibrator (a coefficient of an equation for calculating a correction amount of a frequency shift or the frequency shift corresponding to the temperature) and provides information to be used for correcting the frequency shift to the system device processing unit 2.
