Nowadays in general the so-called "dead vote" is disliked and unpopular. But the electoral systems in which electors take no notice of dead vote are known to us. They are the majoritarian representation system, above all things the single-member district system, in other words first-past-the-post system. Here the focus is brought on the representation of the whole people, accordingly the integrated Will of the People. On the contrary, in the proportional representation system the reflection of the Will of the People, in reality of each party composing the Will of the People is aimed at. Its motive is to decrease the dead vote. But by overdecreasing appeared the unstable multi-parties political situation. Consequently, newly the technique to produce the dead vote, for example so-called exclusion barrier clause, was tried. In this essay I have intended to see about not only the minusimages, but also the significance of the dead vote.
