A crack control structure of an opening using a fiber reinforced mortar hardener is provided to make construction simple, to control the crack of an opening regardless of the anchorage length, to control the crack initiated from the corner of an opening, to prevent the lowering of usability of a structure by a water leakage, and to make an elevation design of a structure freely without installing a separate crack induction joint. A crack control structure of an opening for controlling cracks around an opening(10) of a concrete structure is formed by installing fiber reinforced mortar hardeners(20), formed by mixing fiber to mortar and hardening in the plate type, to the inside of a wall at a certain distance from the corner of the opening.
