摘要：
A structure containing polyhydroxyalkanoate and a magnetic substance includes an external phase part containing polyhydroxyalkanoate and an internal phase part contained in the external phase part, at least one of the external phase part and the internal phase part containing a magnetic substance. Accordingly, provided is a microcapsule, which can be suitably used for formation of an active ingredient of a sustained release pharmaceutical preparation or an ultrasonic contrast agent.
