The filter element (1) has an annular filter body (2) made of folded sheet material. End folds of the filter body are directly or indirectly connected with each other in a circumferential direction for forming a rotation positional alignment of the filter element with a connection area (7). Geometry of the connection area is different from that of adjoining folding regions (8) of the filter body in the circumferential direction. The connection area is extended along the entire filter body in an axial direction and along a portion of the filter body in the circumferential direction. An independent claim is also included for a filter device. |
