To provide an umbrella bag that is not lost and an umbrella bag that can be carried as an umbrella shoulder case by being hung on a shoulder, solving the problem with a conventional umbrella bag that although an umbrella bag is necessary because if a wet umbrella is carried in a vehicle after rain, it causes much trouble to others, there is a possibility that an umbrella bag is lost as it is detached from the umbrella when it rains.

One mouth of an umbrella bag which is formed by making waterproof cloth cylindrical with a line fastener is called an upper part, and the other mouth is called a lower part here. A plurality of rings are attached to the lowest part of a slider of an automatically opening/closing umbrella, which is sewn to the upper part of the umbrella bag. The umbrella bag includes a funnel-shaped raindrop collector with a raindrop outlet at its leading end at the lower part of the umbrella bag, and a hook to be connected with a rib. Loss of the umbrella bag is prevented by integrating the umbrella and the umbrella bag.
