A method for estimating an arrangement of electrodes obtains detection signals when an initial electrode array having a sufficient number of electrodes for detection of excitation wave arranged and arrayed in a plane is attached to biological tissue. The method uses a plurality of input data based on detection signals obtained in a plurality of second electrode arrays generated by eliminating a predetermined number of electrodes at random from the initial electrode array, and uses an image of excitation wave in a process of obtaining the detection signals by using the initial electrode array, as teacher data, obtaining a learned model by deep learning. The method selects a second electrode array corresponding to an analysis image that is best matched with the image of the teacher data, among a plurality of analysis images obtained by applying the plurality of input data to the learned model, as a selective electrode array.
