A substrate includes a support layer, a column-shaped first bump, and a second bump. The support layer has a main surface. The first bump is filled with a first conductive metal and also has a first upper surface and a side surface. The second bump includes a plurality of fine particles formed of a second conductive metal and also has a third portion configured to cover the first upper surface and a fourth portion configured to cover a part of the side surface. The first bump is disposed on the main surface, or the first bump is connected to an electrode disposed on the main surface. The second bump has a convex second upper surface. A height of the fourth portion in a direction perpendicular to the first upper surface is smaller than that of the first bump.
