Belt cover

A girth cover for attaching a saddle for riding to a horse, comprising at least the following (1) to (3):

• (1) an electrode for detecting a bioelectric signal by contacting with the surface of a body of the horse,
• (2) an electric wiring, and
• (3) a connector for connecting with the electric wiring through a part for connecting with the connector and the electric wiring,
• wherein each of the electrode and the electric wiring comprises a stretchable conductor comprising a conductive particle comprising a silver particle and a binder resin,
• the stretchable conductor of the electrode and the electric wiring has a sheet resistance of 0.1Ω□ or less,
• an insulating layer is laminated on the electric wiring, and
• the electrode and the electric wiring are integrally formed without joints which prevents the electric wiring from being disconnected during physical activities of the horse and also prevents water or sweat from the horse from entering between the electrode and the electric wiring which makes it possible to continue to trace the physical activities of the horse at times of rainfall and also at times of the physical activities being intense, resulting in the sweat from the horse,
• wherein the electrode, the electric wiring, and the part for connecting with the connector and the electric wiring are formed from a stretchable conductor sheet composed of the stretchable conductor,
• wherein the stretchable conductor sheet constituting the electrode, the electric wiring, and the part for connecting with the connector and the electric wiring has a thickness of from 0.02 mm to 2.0 mm, and
• wherein the connector is connected with at least one device selected from any one of the following b) to d):
• b) a device for memorizing the bioelectric signal to be detected,
• c) a wireless communication device for transmitting the bioelectric signal outside, and
• d) a device for providing a power.
