PROBLEM TO BE SOLVED: To provide a syringe connector capable of easily and appropriately connecting a syringe to a container-side attachment attached to a container for holding a drug. SOLUTION: A syringe connector 100 is a connector that can be connected to a container-side attachment 200 that is attached to two or more containers 410 and 420 that hold a drug, and can be connected to a tip portion 311a of a first syringe 310. The container can be connected to the first connecting portion 110 that enables the first syringe to be connected to the first connected portion 221a provided in the container-side mounting tool, and the tip portion 321a of the second syringe 320. It has a second connecting portion 120 that enables the second syringe to be connected to the second connected portion 221b provided on the side attachment, and a connecting portion 130 that connects the first connecting portion and the second connecting portion. The shape of the connecting portion and the shape of the second connecting portion are configured to be different from each other.
