There is provided a strengthened glass capable of shortening a process time for maintaining the strength to improve the production efficiency and forming an edge surface of the strengthened glass in any shape while preventing damage such as fracture due to micro-cracks or the like. Strengthening layers 2 are formed on both surfaces of the glass plate 1, and protection films 3 are formed in regions except for cutting portions 4. Subsequently, recessed portions 7 are formed by etching both surfaces of the glass plate at the cutting portions 4 of the glass plate 1 not covered by the protection films 3. Subsequently, the glass plate 1 is cut using a cutter 8 along the recessed portions 7 to form separated strengthened glass 10, and a stepped portion 11 having a protruding cutting surface and including an interior side surface 12 formed by etching a periphery of the glass plate 1 and an exterior side surface 13 formed by mechanical cutting is formed. Also, an edge portion of the stepped portion 11 may be formed in any shape by mechanical machining.
