A module includes a substrate including a first main surface, a first component mounted on the first main surface, a first sealing resin that covers the first main surface and a portion of connection of the first component to at least the first main surface, a first conductor pattern arranged on a surface of the first sealing resin on a side distant from the first main surface, and a columnar conductor as a metal member connected to the first conductor pattern to pass through the first sealing resin from an electrode drawn from the first component along the first main surface.

Module

A module board includes a base substrate. Electronic components are mounted on a first principal surface of the base substrate. The mounted electronic components are sealed by a sealing resin containing an SiOfiller. A top surface and side surfaces of the sealing resin are covered with a shield layer containing a carbon filler, which is flat powder, as a conductive component. A terminal electrode is formed on a second principal surface of the base substrate that is disposed opposite to the first principal surface of the base substrate.

Module board

An electronic component module includes a circuit substrate including surface mount components mounted thereon, a resin layer embedding the surface mount components, and a conductor layer provided on a surface of the resin layer, wherein a conductive post is provided on the surface mount component, and an external electrode having a ground potential provided on the surface mount component is conductively connected to the conductor layer through the conductive post, whereby the conductor layer defines a shielding layer.
