Claim 8:
9. The method of claim 1, wherein, in the obtained starch-containing microspheres, more than 90 wt % of the starch-containing microspheres are in a concentrated distribution range that is within the range of 0.1-500 μm, and when the concentrated distribution range is divided into a plurality of intervals, a proportion of microspheres in each interval is as follows:, 1
