The invention discloses a gas-liquid shunting vapor chamber with a directional fingerprint-imitating capillary structure, which comprises an upper cover and a lower cover, the edge of the lower cover is used for being hermetically connected with the edge of the upper cover of the vapor chamber, and a cavity for airflow circulation is formed between the upper cover and the lower cover. A plurality of micro-structure capillary grooves distributed in the length direction of the cavity are formed in the portion, corresponding to the bottom of the cavity, of the lower cover, fingerprint-imitating capillary structures are arranged between the micro-structure capillary grooves in the portion, corresponding to the heating source area, of the lower cover, and the fingerprint-imitating capillary structures comprise a plurality of arc-shaped or V-shaped micro-structure capillary connecting grooves. The fingerprint-imitating capillary structure is arranged at the position, corresponding to the heating source area, of the
