PROBLEM TO BE SOLVED: To provide toilet stool equipment which uses a radio signal, constituted by superimposing a pulse train on a carrier wave, for communication between a toilet stool and a toilet seat unit, and which can determine whether a received state of the radio signal in a reception part is good or not. SOLUTION: A transmission part 3 for transmitting the radio signal is provided on a transmission side. The reception part 41 for receiving the radio signal so as to convert it to an electric signal, a filtering part 42 for filtering the electric signal, a waveform shaping part 43 for shaping a waveform, an integration part 44 for performing integration, and a comparison and output part 45 for comparing a pulse with a threshold and outputting the pulse when the pulse exceeds the threshold are provided on a reception side. The toilet stool equipment performs a prescribed operation depending on a restoration signal composed of the pulse train output from the comparison and output part 45. The toilet stool equipment is provided with a determination part 46 which determines the received state of the reception part 41 by the width of the pulse output from the comparison and output part 45, when the pulse with the predetermined width, transmitted from the transmission part 3, is received by the reception part 41.
