A carrying case for an electronic device includes a main compartment receiving the electronic device and having an opening as an entrance, a cover foldably fixed on the main compartment for covering the opening, a first supporting member positioned on the cover and a second supporting member positioned on the cover and spaced from the first supporting member, a first engaging member and a first fixing member. The first supporting member and the second supporting member are capable of forming a V-shaped ridge structure when the cover is partially elevated above the main compartment and supporting the electronic device. The first engaging member is fixed on the first fixing member to maintain the V-shaped ridge structure.
