Abstract. We introduce to the notion of almost $\sigma$-continuity on $\sigma$-structures and investigate the relation among $\sigma$-continuity, weak $\sigma$-continuity and almost $\sigma$-continuity. We also investigate characterizations for such continuity by using $\sigma$-semiopen sets, $\sigma$-preopen sets, $\sigma$-$\beta$-open sets, $\sigma$-regular open sets, and $\sigma$-$\delta$-open sets.
