Abstract: An analyzer to carry out a reaction with efficiency is provided. A substrate and a cover member having a concave portion to form a space for retaining a reaction solution are constructed of deformable material, the cover member is deformed by exerting a force externally of the cover member, and the reaction solution introduced into the space for reaction is moved within the space by this deformation, thereby allowing the reaction solution to be stirred within the space. Enhancement of signal intensities is achieved by improvement of reaction efficiency due to mixing. Further, uniform mixing can be achieved over the entire region within the space because an arbitrary location of the cover member can be deformed.
