An electrophysiology catheter, comprising an inner tube and an outer tube connected in a sleeving mode, wherein the inner tube and the outer tube are movably relative to each other, and the inner tube and the outer tube are connected with each other by an electrode assembly which comprises:

• a plurality groups of base body groups which are arranged in a circumferential direction of the inner tube, wherein the base body group connects the inner tube with the outer tube and comprises two or more base bodies distributed at intervals in the circumferential direction of the inner tube, the base body is deformable and at least comprises a first segment and a second segment connected with each other, the first segment and the second segment have a first connecting point, the first connecting points of a same base body group are in contact connection with each other to form a junction;
• and
• electrodes which are at least disposed at the junctions.
