To provide a biological signal measuring device which can detect a significant biological signal without causing a person to feel uncomfortable. A configuration is adopted where elastic members made of expanded rein beads 20 and 30 having a size covering air cushions 10 are disposed between a skin member and the air cushions 10 of a human body supporting device. By providing the elastic members made of expanded rein beads 20 and 30, foreign obj ect feeling due to loading the air cushions 10 is eliminated. By arranging a plurality of elastic members made of expanded rein beads 20 and 30 in a stacking manner, preferably, arranging two elastic members made of expanded resin beads, spring constants of the elastic members obtained from load-deflection characteristics when they are pressed to a deflection amount of 1mm by a pressing plate with a diameter of 30mm being higher than that of the air cushion and being different from each other, a biological signal can be transmitted to the air cushions 10 without damping the biological signal, though the elastic members made of expanded rein beads 20 and 30 are provided. |
