We discuss how to use teaching materials of video and manga in computer ethics education of universities. The features of those teaching materials and the learning effect by using them are also discussed. In 2009, some of the video teaching materials are converted to manga version, and those mangas were used before and after the video watching in the education of Hokkaido University. It is found that the learners were interested in the way of using both video and manga during the course of learning. The learning effect was also shown up by their repetition study. It was clarified that the teaching material that the learner wanted to learn first depended on the difficulty of the learning item and learner’s learning style.
