Abstract：
Let $\[{M^n}(n \ge 2)\]$ be a complex Kaelaler submanifold immersed in the complex projective space $\[C{P^m}(1)\]$. Let $K$ be the sectional curvature of $\[{M^n}\]$. Then $\[K \ge 1/8\]$ if and only if $$\[{M^n}\]$$ is
an imbedding submanifold congruent to the standard imbedding $$\[C{P^m}(1)\]$$ or $\[C{P^n}(\frac{1}{2})\]$.
