Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a signal transmission device capable of making a circuit scale small even when handling a plurality of analog signals. SOLUTION: The signal transmission device results from improving a signal transmission device receiving first and second analog signals and includes: an oscillator which receives the first analog signal and oscillates a triangular wave by the first analog signal; a pulse width modulation signal generator which receives an output of the oscillator and the second analog signal and converts its output to a pulse width modulation signal proportional to a level of the second analog signal; and a signal processor which obtains a duty ratio and a frequency of the pulse width modulation signal from the pulse width modulation signal generator.
