Abstract

A module includes a substrate, a first component, and a first sealing resin layer. The substrate includes a first principal surface. The first component is mounted on the first principal surface. The first sealing resin layer contains a filler containing an inorganic oxide as a main component. The first sealing resin layer is provided on the first principal surface. The first sealing resin layer seals the first component. A marking portion is provided on a surface of the first sealing resin layer on a side opposite to the substrate. In the first sealing resin layer, the content rate of the filler is smaller in a second portion on the side opposite to the substrate than in a first portion on the substrate.
