Abstract: A manufacturing method of a mounting substrate includes: preparing a substrate including a mounting portion having a mounting surface, a first protruding portion having a first upper surface located above the mounting surface, and a second protruding portion having a second upper surface located above the mounting surface, the mounting surface being located between the first and second upper surfaces in a top view; disposing the substrate on a support member having a support surface such that the first and second upper surfaces face the support surface; and providing first and second through holes from a lower surface side toward an upper surface side of the substrate at first and second positions between which the mounting surface is interposed in the top view, the first and second positions not being located between the first upper surface and the mounting surface nor between the second upper surface and the mounting surface.
