The present invention relates to a method for injecting carbon dioxide to produce a carbonated drink. According to the present invention a drink composition having a temperature of 10�C to 30�C is introduced into a container and then solid or liquid carbon dioxide having a temperature of 78.5�C to 5�C is injected into the drink composition having the temperature of 10�C to 30�C and introduced into the container whereupon the container is immediately sealed. In the method for injecting carbon dioxide to produce a carbonated drink according to the present invention when the carbonated drink is produced even though carbon dioxide content is increased in a state where a large amount of the drink is contained in a container having a predetermined volume the added carbon dioxide changes little in temperature and saturated vapor pressure. As a result bubbles do not occur in the drink the drink does not overflow and the carbon dioxide does not evaporate. Also since the container is sealed in a state where the carbon dioxide has little saturated vapor pressure the drink may be filled up to the portion close to the cap for sealing so as to reduce the size of the container such as a bottle or a can as compared to the typical size of such a container.
