Abstract: The present invention provides cells which have a high ability to propagate influenza virus, are suitable for use in production of an influenza virus for preparing a vaccine, and are able to be cultured in vitro, and a method for producing an influenza virus using the cells. That is, the present invention provides cells for producing an influenza virus in which expression of one or more genes that encode proteins involved in an effect of suppressing influenza virus production in a cell is suppressed and the gene is at least one selected from the group including ACTG1 gene and the like, and a method for producing an influenza virus that includes infecting the cells for producing an influenza virus with an influenza virus and then culturing.
