This invention relates to a balloon holder comprising an external cap having a slit through which a string is pulled out, and an internal cap to be fitted to the external cap. When the holder is fitted to a balloon, the total weight of the holder is greater than buoyancy of the balloon. Accordingly, the balloon does not fly away when one lets the string go. The length of the string can be adjusted or the string can be fixed to prevent string pull-out by rotating the external and internal caps.
