Zusammenfassung:	To provide a sintered body having improved plastic deformation resistance at high temperature, and a friction agitation bonding tool including the same.SOLUTION: A sintered body has a first hard phase and a binder phase. The first hard phase is composed of WC. The binder phase has, as its main component, a first metal comprising at least one selected from Co and Ni, a second metal comprising at least one selected from Al and W, and C.SELECTED DRAWING: Figure 1 【課題】高温での耐塑性変形性が向上した焼結体、および、それを用いた摩擦攪拌接合ツールを提供する。【解決手段】焼結体は、第１硬質相および結合相を含む。第１硬質相はＷＣからなる。結合相は、主成分としてＣｏおよびＮｉから選択される少なくとも１種からなる第１金属を含み、さらに、ＡｌおよびＷから選択される少なくとも１種からなる第２金属と、Ｃと、を含む。【選択図】図１
