description An IDT electrode includes: a first busbar, a second busbar facing the first busbar, multiple first electrode fingers electrically connected to the first busbar, multiple second electrode fingers electrically connected to the second busbar and arranged in an alternating manner with the multiple first electrode fingers in an acoustic wave propagation direction, multiple bar electrodes interposed between the first busbar and the multiple first electrode fingers, and extending parallel to the first busbar and parallel to each other, multiple connection portions including a connection portion that is interposed between the first busbar and a corresponding one of the bar electrodes adjacent to the first busbar and that connects the first busbar to the corresponding bar electrode, and a connection portion that connects adjacent bar electrodes to each other. Some of the connection portions are disposed in a discontinuous manner with respect to an extension direction of the multiple electrode fingers.
