PURPOSE: A connector having a bending groove and a cubic building block for study using thereof are provided to perform the accurate-angled coupling of each connecting pipe and each connecting piece of a cubic building block by making the connecting piece capable of being bent at a specific portion and to perform dynamic movement of the cubic building block. CONSTITUTION: A connector having a bending groove(10) comprises a body(12) which includes a penetration-hole at the center; a plurality of connecting pieces(14) which is radially extended from the body for being coupled to connection pipes; a connection bending groove(15) which is formed on the boundaries of the connecting pieces and the body such that the connecting pieces are bent at specific portions; and a body bending groove(16) which is formed for bending the body entirely at the specific portion.
