The invention belongs to the field of solid-state atomic magnetometers and the field of micro-nano processing and manufacturing, and especially discloses an integrated small-size NV color-center solid-state magnetometer and a manufacturing technology therefor. The method comprises the steps: carrying out the polymer packaging of a diamond block comprising an NV color center, and forming a resonantmicrocavity; integrating related functional devices of an ODMR test through the miniature assembly technology, including a laser diode, a microwave antenna and an interference cut-off filter. The integrated system enables the diamond and the microwave antenna to be integrated into the resonant cavity, and the laser diode is disposed at the top of the diamond and is used for directly generating laser with the length of 532nm so as to activate the NV color center in the diamond to generate fluorescent light. The system can achieve the better capturing of 532 laser, enables the laser to be totally reflected in the cavity for many times, enables the microwave antenna and the diamond to be wrapped in the cavity at the same time, and achieves the high-efficiency collection of laser fluorescentlight signals. The above system can achieve the high-sensitivity magnetic measurement.
