An object of the present invention is to provide a storage device for a balloon catheter, capable of protecting the balloon catheter from damage which would otherwise be caused by a stylet that protects a tip portion of the balloon catheter. A storage device 100 for a balloon catheter includes a stylet 75 to be inserted into a guidewire lumen 51 of a balloon catheter 10, a balloon cover 80 that surrounds a folded balloon 20 of the balloon catheter 10, and a fixture 90 that regulates a rear end position of the stylet 75 with respect to a rear side opening 54 of the guidewire lumen 51 by fixing the stylet 75 to the balloon cover 80 at a position apart from a tip portion of the balloon catheter 10.
