PURPOSE:To make it possible to prevent a photometric mistake and a dripping mistake, by forming an analytical unit into such a configuration that said unit can not be inserted in the insert part of a biochemical analyser in a state of turning inside out. CONSTITUTION:An analytical element 1 is constituted of a mount cover 102, a mount 3 and a chemical analysis film 2. The film 2 is constituted by forming a reagent layer 2b to the upper surface of a transparent support 2a and laminating a developing layer 2c to the upper surface of said reagent layer 2b. The squeezed part 10 capable of mounting the chemical analysis film 2 is provided to the central region of the mount 3 and the film 2 is adhered to the mount by an adhesive means with an adhesive. Because of this configuration, the element 1 is asymmetric in the upper and lower sides thereof. The insert port of a biochemical analyser is also constituted so as to be asymmetric in the upper and lower sides thereof and the element can not be inserted in said insert port in a state of turning inside out.
