Abstract. We give an affirmative answer to the following conjecture of Ma. Kato: Let $S$ be a compact complex surface in Kodaira's class $\mathrm{VII_0}$ which contains a strictly positive number of rational curves being exactly equal to the second Betti number of $S$. Then $S$ admits a global spherical shell.
