The invention discloses an intrusive microneedle and an intrusive method thereof, and relates to the technical field of biomedical engineering.By means of the design that a soft needle body is wrapped by a second reinforcing layer and a first reinforcing layer, the soft needle body can be integrally reinforced, the reinforcing structure is simple, the distance between needle tip parts is fixed, and the intrusive microneedle is convenient to use. The reinforced soft needle body can be implanted by using simple implantation equipment without complicated implantation equipment, through the degradable design, after implantation, the second reinforcing layer and the first reinforcing layer can be automatically dissolved in tissue fluid, and only the soft needle body with good flexibility and small size is left in a living body, so that the soft needle body is convenient to use. The long-term injury and risk of the invasive microneedle to organisms are greatly reduced, the structure is simple, the use is convenient
