Abstract: A junction body has a first member and a second member each of which is provided with a joining surface whose main component is copper. A solder member containing, in a tin-base solder material, a three-dimensional web structure whose main component is copper is provided between the first member and the second member. A copper-tin alloy whose average thickness is 2 μm or more but 20 μm or less is provided between the joining surfaces and the three-dimensional web structure.
