1. A dissimilar material joint including a plurality of segments arranged consecutively in a longitudinal direction, each segment comprising: a first member; an intermediate member formed of a material different from a material of the first member, the intermediate member being joined to the first member in a stacking direction by explosive welding; a second member formed of a material different from the material of the first member and different from the material of the intermediate member, the second member being joined to the intermediate member in the stacking direction by explosive welding; and a recess formed in a joint end face joined to another one of the segments, the recess spacing apart an end face of the first member and an end face of the second member from each other in the stacking direction along the joint end face, wherein the end faces of the respective first members of the segments that are adjacent to each other are joined together by welding, the end faces of the respective second members of the segments that are adjacent to each other are joined together by welding, and each of the segments includes hollow space formed at a position that is set back from the joint interface further than the recess in the longitudinal direction, the hollow space spacing apart the first member and the second member from each other in the stacking direction.
