This study aims at looking around the whole aspect of women\'s epic in Che-ju island. Generally, Dang-bonpuris(당본풀이) have not a whole-life-style, but a lot of Dang-bonpuris that accept \'heroic-whole-lifetime\' structure, show narrative enlargement. Ilban-bonpuris(일반본풀이) that sing the origin of goddess, generally has a whole-lifetime-style, but the heroine characters are not singular. On the whole, there are two groups, that is the type of accentuating goddess authority and the type of accentuating woman\'s bitter. From these facts, we can infer that formation and change of women\'s epic get accomplished by literary-internal cause and literary-external cause. The former is the fact that it goes with an epic genre. The point is the acceptance of \'heroic-whole-lifetime\' structure. The latter is the fact that ideas of women have changed with the changes of the times. These changes of ideas would have an influence on the women\'s epic through three steps. First step is revealed through a godmother‘s character of the primitive goddess, next step shows a character that has a motherhood of ancient goddess and heroine, and the last step is revealed through a dependent character of medieval heroine. We can think that these changes of ideas would make women\'s epic abundant.
