Abstract: [PROBLEMS] A fishing rod case that can be used for a fishing rod independent of the length of the rod when it is retracted, that can be carried in a form that is as compact as possible according to the length of the fishing rod, and that can sufficiently protect the fishing rod from external force applied while it is carried. [MEANS FOR SOLVING PROBLEMS] An outer case (3) has an opening (4) at one end in the left-right direction. An inner case (2) has an opening (13) at one end in the left-right direction. The opening (13) side of the inner case (2) is inserted into the outer case (3) with the other end of the inner case (2) projected outward from the opening (4). The extent of insertion in the left-right direction of the inner case (2) into the outer case (3) is adjustable. An engagement section (11) formed on either the inner case (2) or the outer case (3) is engaged with an engagement receiver (7) formed in the other, thereby the casts are positional fixed after the extent of insertion is adjusted.
