The invention discloses a self-adaptive electrode wall surface micro-nano pit micro-bubble generating device and a manufacturing method thereof and relates to the technical field of active drag reduction of underwater vehicles. The device comprises a substrate and a direct-current power supply, a surface of the substrate is provided with an electrode wall surface micro-nano pit, a wall surface ofthe electrode wall surface micro-nano pit and an upper surface of the substrate are provided with a sputtering metal layer, the sputtering metal layer on the upper surface of the substrate is coveredwith photoresist, and the sputtering metal layer is connected with a negative electrode of a direct-current power supply through power supply wires. By electrolyzing an NaCl solution, micro-bubbles can be supplemented in a self-adaptive mode, continuous and long-time ventilation is not needed, when the micro-bubbles are broken or a gas-liquid interface is lower than an upper end of the laid sputtered metal negative electrode, the device automatically triggers an electrolysis circuit, self-adaptive control of the micro-bubbles is achieved, and the device is suitable for surface ships and underwater vehicles. The micro-bubbles can be stably maintained, and a practical application is facilitated.
