PROBLEM TO BE SOLVED: To provide a biodegradable particle which can be formed without causing aggregation or cohesion of particles, and can be delivered to a target site without causing the aggregation or viscosity increase in blood vessel or a tool such as a catheter, a needle or an injector, smoothly degraded after a specific period to form the final decomposition component absorbable in the body or exhausted from the body without leaving the component in the body.
SOLUTION: The biodegradable particle has a particle diameter of &ge5&mum and is coated its surface with a polyalkylene glycol.
