Various organismus in the world receive several kinds of informations from their environments and use them for decision making. However, when an informationis shown, some one receives it willingly though the others put it aside as of no use. This fact show that the measure of the value of information must be introduced by taking account of the receiver's inherent criterion. This means that the value of information is evaluated subjectively contrasting with the measure of the amount of information established by Shannon, which is a completely objective concept. In this paper, the theory of the value of information and accompanied decision making are discussed. Here, a quantity representing the level of knowledge of the receiver that is an expected loss of the average profit due to the lack of sufficient information is introduced, and then the value of information is defined as the difference of a prior and posterior level of knowledge. A few cases concerning the ways to receive informations are discussed.
