PROBLEM TO BE SOLVED: To provide an imaging element and a method for manufacturing the same, which can obtain a desired absorption peak wavelength without depending on experimentation and which can equalize the sensitivity of the absorption peak, in the imaging element having a light absorption layer with respect to the depth direction from the surface of the element. SOLUTION: The imaging element is characterized in that the light absorption layer is formed of the material of which the absorption coefficientα(λ) with respect to the light having the wavelengthλis strictly or approximately expressed by an expressionα(λ)=α<SB>0</SB>exp(-βλ), which is formed in a region at X=X<SB>0</SB>(1±γ) from the surface of the element, where X is the depth from the surface of the element, and in which the values of X<SB>0</SB>andγsatisfy an expression (3), with respect to the prescribed absorption peak wavelengthλ<SB>m</SB>.
