Abstract: A module improves a heat-releasing effect and that can be stably mounted on a mother substrate or the like. The module includes: a first component mounted on one main surface of a wiring substrate and generates heat; second components mounted on the one main surface of the wiring substrate; a sealing resin layer that seals the first component and the second components so as not to cover a top surface of the first component; and heat-dissipating parts arranged on the top surface of the first component. The height of the highest positions of the heat-dissipating parts relative to the one main surface is less than or equal to the position of a highest surface out of a surface of the sealing resin layer that is on the opposite side from the surface of the sealing resin layer that faces the one main surface.
