A graph $G$ is $H$-saturated if it contains no $H$ as a subgraph, but does contain $H$ after the addition of any edge in the complement of $G$. The saturation number, ${\rm sat} (n, H)$, is the minimum number of edges of a graph in the set of all $H$-saturated graphs of order $n$. We determine the saturation number ${\rm sat} (n, P_6 + tP_2)$ for $n \geq \frac {10}{3} t + 10$ and characterize the extremal graphs for $n > \frac {10}{3} t + 20$.
