Patent ID: 7659110

Claim:
A DNA amplification device, wherein, in a DNA amplification device equipped with a processing block, which has cells that can contain a reaction solution including a DNA sample, respectively, a thermo-module(s) using peltiert elements for heating and cooling the processing block, and a controller that controls the electrification at least to the thermo-module(s), wherein the processing block is comprised of a base, which is constructed by adhering an upper substrate formed with a metal material and a lower substrate formed with a metal material or a ceramic material, and the cells supported by this base; and the cells are secured to the upper substrate and/or the lower substrate via at least cell positioners established in the upper substrate for positioning the cells, and at the same time, at least the thickness of the regions situated under the cells in the lower substrate is selected to be 1.0 [mm] or thinner, and, the thermo-module(s) comes into contact with the lower surface of the base.
