Abstract
In one embodiment, an antiviral material includes at least one microparticles selected from tungsten oxide microparticles and tungsten oxide composite microparticles. The microparticles have an inactivation effect R of 1 or more expressed by [R=log C−log A], when there is evaluated a virus titer by inoculating on a specimen to which the microparticles are adhered, at least one virus selected from a low pathogenic avian influenza virus (H9N2), a high pathogenic avian influenza virus (H5N1) and a swine influenza virus, and irradiating the specimen with visible light having a wavelength of 380 nm or more and illuminance of 6000 lx. for 24 hours.
