To provide a plate for biological sample analysis that amplifies and analyzes DNA and certainly transports amplified PCR (Poloymerase Chain Reaction) reaction liquid to a sample quantity determining section.

By disposing a slope on a part of a wall surface of a reaction chamber, the reaction liquid can be moved along the slope to the bottom surface. Therefore, the PCR reaction liquid can uniformly cover the bottom surface of the reaction chamber, so that the liquid feeding to a sample quantitatively determining section can be performed certainly.
