Abstract
A filter element (), with a preferably multilayer structure of a filter medium (), in pleated form has filter pleats () of different pleat heights (h, h). The filter pleats () with a first pleat height (h) oppose the filter pleats () lower second pleat height (h). The filter element has a throughflow direction for fluid to be cleaned away from a dirty side to a clean side (R). The transitions arranged adjacent to the inner side all conclude along a fictitious circular cylinder (), which penetrates the filter medium () coaxially to its longitudinal axis (LA).
