A laminated film containing a gas barrier layer and an inorganic polymer layer laminated on a resin substrate, wherein a Y value calculated from a transmission electron microscope image of a cross section of the inorganic polymer layer by the following procedures (a) to (d) is 0.220 or less: (a) Calculating a standard deviation (&#x3c3;) of the contrast of an electron beam-unirradiated part of the inorganic polymer layer; (b) Dividing an electron beam-irradiated part of the inorganic polymer layer into twenty parts having a film thickness equal in a film thickness direction, and calculating a standard deviation (an: standard deviation of ndivision, n=1&#x2dc;20) of the contrast of each divided part; (c) Calculating Xn (n=1&#x2dc;20) of each divided part from the expression (1): Xn=&#x3c3;n/&#x3c3; (n=1&#x2dc;20) . . . (1); and (d) A standard deviation of X3 to X18 is defined as Y.

Laminated film and process for manufacturing the same, as well as method for analyzing laminated film

Disclosed is a photoelectric conversion element comprising an anode, a cathode, and an active layer between the anode and the cathode, wherein the active layer includes an n-type semiconductor and a p-type semiconductor, and an area of a p-n junction between the n-type semiconductor and the p-type semiconductor is 100 &#x3bc;mor more per 1 &#x3bc;mof the active layer.
