PROBLEM TO BE SOLVED: To provide a material having a myocardial tissue-like structure consisting of cultured cells and nobel motion characteristic not obtained in the past, and a manufacturing method therefor.;SOLUTION: The self-movable film of myocardial tissue-collagen 23 contains film-like collagen 15 and a myocardial tissue-like structure 12 consisting of cultured cells, The myocardial tissue-like structure 12 is formed on an upper surface and/or a lower surface of the film-like collagen 15. The film-like collagen 15 and the myocardial tissue-like structure 12 are undetachably integrated. The self-movable film of myocardial tissue-collagen 23 has self repetition fluttering motility.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
