<P>PROBLEM TO BE SOLVED: To provide a signal receiving device capable of outputting signals corresponding to feeble signals. Ž<P>SOLUTION: The signal receiving device includes: a first voltage/current conversion part, provided with a first input end to which voltage signals and a reference voltage are superimposed and inputted and a first output end, from which the voltage signals and the reference voltage superimposed and inputted to the first input end are voltage/current converted and outputted; a second voltage/current conversion part, provided with a second input end to which the reference voltage is inputted and a second output end, from which the reference voltage inputted to the second input end is voltage/current converted and outputted; a current mirror circuit, provided with a third input end, to which a current outputted from the second output end is inputted and a third output end from which the current corresponding to the current inputted to the third input end is outputted; and an output part connected to both of the first and third output ends.
