A stent for a confluent blood vessel of the present invention comprises: a plurality of first wires which consist of a number of rows in one direction and of which the shape is maintained inside a human body a plurality of second wires which intersect with the first wires and are formed as a number of rows and a connector which connects the portion where the first wires and the second wires intersect with each other, wherein a plurality of hollows are formed by the first wires and the second wires, and at least one of the plurality of second wires is decomposed after a predetermined time inside the human body. Accordingly, the following effects are anticipated: when removing the stent, removal is easy because the second wires consisting of the biodegradable polymer are gradually decomposed by bodily fluids and a stent insertion effect can be expected to be sustained for a long time because the shape of the stent is maintained over a predetermined time. In addition, as drugs are sequentially released during the decomposing process of the second wires, there is an effect of drugs being continuously released.
