Abstract: Temperature uniformity of a reaction liquid in a plurality of reaction containers of an automatic analysis device is maintained by a heat block. A strip-shaped heater heats the heat block, and is wound and attached on an outer circumference of the heat block so that both end regions of the strip-shaped heater are adjacent to each other. The strip-shaped heater includes a heat generating resistor that is heated by applying an electric current, an insulating film sandwiching the heat generating resistor, and first and second electrical feed lines that are attached to both end portions of the heat generating resistor and supply power to the heat generating resistor. The width of the heat generating resistor in both end regions of the strip-shaped heater is formed to be narrower than the width of the heat generating resistor in the other region thereof.

Abstract: Provided is a highly reliable temperature adjustment apparatus which uses a temperature adjustment element and quantitatively evaluates the temperature adjustment performance of the temperature adjustment element. The temperature adjustment apparatus is provided with: a temperature adjustment element; one or more temperature detection elements provided near the temperature adjustment element; a calculation unit for calculating the output of the temperature detection element; and a display unit for displaying at least one of a time calculated by the calculation unit as a time at which the temperature adjustment performance of the temperature adjustment is predicted to be below a desired level, the number of operations and the time of current conduction or a warning based on the result of calculation.
