Provided a ground drilling device capable of reducing the maintenance time by suppressing wear of the rotary blade, extending the life of each component, and reducing the frequency of drilling pipes. The ground drilling device (1) includes: the rotary blade (2) that excavates the ground; the lubricating liquid jetting device (3) that jets the lubricating liquid to the rotary blade (2) when excavating the ground, and the oxygen supply device (5) that supplies oxygen to the lubricating liquid, in which the oxygen supply device (5) has the bubble generating medium (6) for supplying oxygen in a high pressure state as fine bubbles to the lubricating liquid.
