The utility model discloses a periodic open-type cross-frame-shaped terahertz wave filter. The periodic open-type cross-frame-shaped terahertz wave filter comprises a signal input terminal, an open-type cross-frame-shaped transmission layer, a matrix and a signal output terminal, wherein the open-type cross-frame-shaped transmission layer is connected with the matrix; the open-type cross-frame-shaped transmission layer includes N*N open-type cross-frame-shaped periodic units, N is a natural number, and each open-type cross-frame-shaped periodic unit includes an open-type square metal frame with a hollowed-out middle part and a cross-shaped metal structure; and signals are input from the signal input terminal, sequentially pass through the open-type cross-frame-shaped transmission layer and the matrix and reach the signal output terminal so that the signals can be filtered. The periodic open-type cross-frame-shaped terahertz wave filter disclosed by the utility model has the advantages of fast response speed,
