A pressing structure of a mouse includes a base, a circuit board mounted on the base, at least one electronic switch mounted on the circuit board, an upper cover mounted on the base, and a button shell. A rear end wall of the at least one opening protrudes downward and extends towards a front end wall of the at least one opening to form a buckling block. A bottom of the buckling block is recessed inward to form a first accommodating groove equipped with a first magnet. The button shell has at least one button. The at least one button protrudes downward to form at least one contact portion. A rear surface of the at least one contact portion is recessed inward to form a buckling space corresponding to the buckling block. The at least one contact portion is equipped with a second magnet.
