PURPOSE:To make tips of pins abut a skin surface of an animal following a shape thereof by providing electrodes which have pins each with a conductive spring bundled side by side and an envelope surface formed by tips of the pins is made variable with the spring. CONSTITUTION:Three electrodes 2, 3, and 4 have leads 5, 6 and 7 bundled into one cord 8 and connected electrically to an electrocardiogram memory 9. The electrodes 2, 3 and 4 have independent seven probe pins 10 (pin) mounted on an assembly case 1 through a spring 11 and the seven probe pins 10 and the spring 11 are housed into an electrode case 12 as insulating body. The probe pins 10 are numbered seven and housed with gaps S thereof held in respective seven sheaths 13. The holding of the gaps S between the probe pins 10 and the sheaths 13 allows the probe pins 10 to move independently. |
