ELECTROCARDIOGRAPHIC WAVEFORM MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrocardiographic waveform measuring apparatus which is not likely to be influenced by electrostatic noise due to a seat body covering material which covers a sensor electrode when the sensor electrode is disposed on a seat body material in an exposed state.SOLUTION: An electrocardiographic waveform measuring apparatus 1 has a sensor electrode 2 disposed on a seat interior side, which is the rear surface of a user contact surface 100h of a separate seat body covering material 101 covering a seat body material 102. The sensor electrode 2 comprises: a first sensor electrode 2X having a first electrode surface 2Xa which is installed on the seat body material 102 and is exposed to the seat body covering material 101 side; and a second sensor electrode 2Y having a second electrode surface 2Ya which is installed on the seat body covering material 101 and slidably comes into contact with the first electrode surface 2Xa.
