Abstract
A valve device for adjusting the flow volumes of a cooling medium and a heating medium for adjusting the temperature of an electronic device includes: flow paths through which a cooling medium and heating medium are able to flow; and a merging section into which these flow path merge. The merging section has a valve shaft internally and a first channel is formed in the valve shaft. The valve shaft makes the first channel face at least two of the flow paths so as to make at least two flow paths communicate with each other.
