The utility model discloses a periodic open-type terahertz wave absorber shaped like the Chinese character 'shen'. The periodic open-type terahertz wave absorber shaped like the Chinese character 'shen' comprises a signal input terminal, an open-type dual-ring metal transmission layer, a matrix and a metal layer structure, wherein the open-type 'shen'-shaped metal transmission layer is connected with the matrix; the open-type 'shen'-shaped metal transmission layer includes N*N open-type 'shen'-shaped periodic units, N is a natural number, and each open-type 'shen'-shaped periodic unit includes an open-type 'shen'-shaped structure; and signals are input from the signal input terminal, sequentially pass through the open-type 'shen'-shaped metal transmission layer and the matrix and reach the metal layer structure so that terahertz waves can be absorbed. The periodic open-type terahertz wave absorber shaped like the Chinese character 'shen' in the utility model has the advantages of simple structure, small size,
