The invention relates to an anode tantalum block and a preparation method thereof. The anode tantalum block comprises a column-shaped tantalum block body. A side wall of the column-shaped tantalum block body is provided with multiple grooves with equal intervals along a radial direction, each groove passes through two ends of the tantalum block body along an axial direction, the depth of each of the grooves is 5% to 80% of the radius of the tantalum block body, and the ESR value of a non-solid electrolyte tantalum capacitor is reduced. The preparation method of the anode tantalum block comprises the steps of pressing tantalum powder to form a green body of the anode tantalum block and carrying out vacuum sintering. The anode tantalum block which effectively reduces the ESR value of the non-solid electrolyte tantalum capacitor is prepared, and the industrial production is facilitated at the same time.
