PROBLEM TO BE SOLVED: To allow easy delivery of a large baggage as well as passage of a wheelchair by allowing an opening width of a doorway formed when a sliding door is to be larger than the sliding amount of the sliding door, related to the sliding door provided at a doorway opening formed on an exterior wall or an interior wall of a building for opening/closing the doorway. SOLUTION: A composite-operation sliding door 30A is provided at a doorway opening H1 which allows both sliding and bending. The composite-operation sliding door 30A comprises a main sliding door 31 which slides under constraint by a guide member such as a slotted rail, and a sub sliding door 32 which is attached to the main sliding door 31 with no constraint by the guide member. The main sliding door 31 and the sub sliding door 32 keep a straight connection attitude between them through a hinge bracket 33 and an attitude constraint member 40, while the sub sliding door 32 bends relative to the main sliding door 31.
