The invention discloses an electrode patch, which comprises an electrode interface, a conductive layer, a conductive connection layer and a current sharing layer, wherein the electrode interface is used for accessing an electric pulse signal, the electrode interface is electrically connected with the conductive layer, and the current sharing layer is electrically connected with the conductive layer via the conductive connection layer. The current sharing layer is preferably a foamed layer, a conductive liquid is absorbed and limited in the foamed layer through the foamed layer to form a uniform conductive path, the current sharing layer is provided with an output surface for surface contact, and the current sharing layer is used for performing current sharing on the inputted electric pulse signal and then outputting the current shared electric pulse signal from the contact surface. A physiotherapy instrument adopting the electrode patch can increase the comfort of the human body, reduce the sensitivity of the human epidermis to the electric pulse signal and create conditions for a stronger and deeper electrical stimulation curative effect.
