Images on the front and rear surfaces of the inserted and coupled board can be completely utilized thanks to a structure in which the whole central portion of the frame, which forms the skeleton, is open, and the durability of the certificate case manufactured in an assembly type can be enhanced by a coupling and fixing pin for fixing the inserted and fixed board, as well as a structure in which the board is detachably inserted into and coupled to an insertion groove formed in the frame. In addition, only a certificate can be replaced separately from the board through a certificate insertion recess that is separately formed in the coupling and fixing pin. |
