This paper shows how people use ideology in advertising discussion. Ideology is much used in the persuasive communication advertisement because it is by nature the mass belief of unconscious and natural agreement. In chapter 2 by whom and how ideology is conveyed and In chapter 3 the real advertisement were analyzed. They are as follows; 1. What is important is that the speaker of ideology-using advertisements is one who became already celebrity as an ideologic symbol through the many different mass media outside the advertisements. 2. In ideology-using advertisements, the linguistic expression is not exposed on the surface but is conveyed in the way which the images already given to the speaker of advertising discussion and used. 3. The choice of speaking style is also chosen in the same way as ideology is conveyed. the object-analyzing advertisements are modestly expressed using ``합쇼체`` becoming on the obedient and self-sacrificing woman and so is I-expression (humble I). Now advertisements are not only the simple reflection of one life but also prescribe even the way of life be giving a new way of life. But advertisements do not show everything but elements contributing to the goods-selling, which is very serous. therefore, it is very meaningful to approach the advertising discussion from the aspect of ideology.
