The new NPB Ball was adapted to the Japanese NPB from this year. Compared with the old NPB ball and new one, seem height and width became 0.2[mm] lower and 1.0[mm] wider respectively. In this report, aerodynamics characteristics are measured by using wind tunnel tests. Some calculations of flight trajectory for pitcher's throwing ball and batter's hitting one are conducted.
