Abstract
The present invention aims to provide a biodegradable particle capable of being molded without an aggregation or cohesion of the particles, capable of being carried or injected without clogging by an aggregation in a micro diameter tube such as of a catheter, needle or syringe mainly used in pharmaceutical and medical applications of which inner diameter is smaller than the particle size or in a blood vessel and capable of being smoothly degraded in a specified period of time so that degraded component can finally be absorbed or discharged in vitro. As means for solving the problem, the present invention provides a biodegradable particle characterized in that a compressive modulus of the particle in water saturated state is 10 MPa or less.
