Abstract
A shadow mask manufacturing method comprising the cleaning step performs rapid cleaning by spraying a cleaning solution, which is inert with respect to the band-like thin metal plate, upon upper and lower surfaces of the band-like thin metal plate and thereby generating cavitation near the surfaces of the band-like thin metal plate by using cavitation jet means, while regulating a position of the band-like thin metal plate and preventing the cleaning solution from leaking in a direction opposite to the conveyance direction of the band-like thin metal plate by using a first leakage-preventing seal unit provided upstream the cavitation jet means.
