PROBLEM TO BE SOLVED: To reduce a mounting load onto a living body, improve aesthetic appearance, durability, and SNR (Signal-Noise Ratio).SOLUTION: A heart-rate/electrocardiographic monitor includes: a terminal 2 having a measurement circuit for performing at least one of heart-rate measurement and electrocardiographic measurement a positive electrode 3, a reference electrode 4, and a negative electrode 5 fixed to a surface of clothing that comes into contact with a living body connectors 7B, 8B, and 9B disposed on an opposite-side surface of the surface of the clothing that comes into contact with a living body and mechanically and electrically connected to the electrodes 3, 4, and 5 connectors 7A, 8A, and 9A disposed on a housing surface of the terminal 2 so as to be fitted with the connectors 7B, 8B, and 9B and electrically connected to the measurement circuit a voltage follower inserted between the positive electrode 3 and the connector 7B for converting impedance of a living body signal received by the positive electrode 3 and a voltage follower inserted between the negative electrode 5 and the connector 9B for converting impedance of a living body signal received by the negative electrode 5.SELECTED DRAWING: Figure 7
