Provided are a method and device for supplying casting sand to a sand hopper (11), whereby attachment of a means for sensing casting sand (17) to the sand hopper (11) can easily be adjusted, and waste can be reduced by controlling the supplying of casting sand through use of the sensing means. This method and device for supplying casting sand to a sand hopper (11) comprises sensing the amount of casting sand (17) in the sand hopper through use of a laser sensor (12) provided to the sand hopper (11), and supplying casting sand to the sand hopper (11) when the sensing result is below a set lower-limit value.
