PROBLEM TO BE SOLVED: To provide an information transmission device capable of transmitting the presence or absence of an abnormality or the state of communication between a sensor or a biological information measurement device and the sensor to the biological information measurement device. An information transmission device includes a biological signal receiving unit that receives a biological signal of a subject measured by a biological sensor, and the biological sensor or the biological sensor based on the biological signal received by the biological signal receiving unit. An abnormality detection unit that detects an abnormality in communication between the biological signal receiving unit and the biological signal receiving unit, and if an abnormality in communication between the biological sensor or the biological sensor and the biological signal receiving unit is detected, is detected by the abnormality detecting unit. And a transmission signal generation unit that generates a transmission signal according to an abnormality in communication between the biological sensor or the biological sensor and the biological signal reception unit, and a signal transmission unit that transmits the transmission signal.
