An estimation device includes a processor configured to: detect an error of data obtained by receiving a wireless signal from a medical device； correct the detected error； determine whether or not there is a noise due to an external generation source at a time of acquiring the wireless signal from the medical device, based on detection information relevant to the detected error or correction information relevant to the corrected error； and estimate a cause of the noise, based on the detection information or the correction information. The detection information is at least one of the number of detections of the error, continuousness of the error, and periodicity of the error, and the correction information is at least one of the number of corrections of the error, continuousness of data in which the error is corrected, and periodicity of data in which the error is corrected.
