A photocatalytic filter and a photocatalytic device are provided. The photocatalytic filter according to an embodiment includes: a plurality of weft threads each of which includes a plurality of fibers extending in a first direction； a plurality of warp threads each of which includes a plurality of fibers extending in a second direction intersecting the first direction； and photocatalysts which are carried by the plurality of weft threads and the plurality of warp threads. At least two warp threads sandwiches at least one weft thread or at least two weft threads sandwiches at least one warp thread at the intersection portion between the weft thread and the warp thread.本發明提供一種可減少壓力損失的光催化劑過濾器以及光催化劑裝置。實施方式的光催化劑過濾器包括：多個橫線部，分別具有在第一方向上延長的多個纖維；多個縱線部，分別具有在與所述第一方向交叉的第二方向上延長的多個纖維；以及光催化劑，由所述多個橫線部、及所述多個縱線部承載。在所述橫線部與所述縱線部交叉的部分，變成至少兩個所述縱線部夾住至少一個所述橫線部、以及至少兩個所述橫線部夾住至少一個所述縱線部的至少任一者。
