Beschreibung
Zusammenfassung:	The present invention provides an electronic component package including an electronic component mounted on a circuit board having a ground pattern, a mold containing an epoxy resin that encapsulates the electronic component, and a shield layer formed on the mold. The shield layer is formed by stacking a metal particle layer, a copper plating layer, and a nickel plating layer in this order from the mold side, and the shield layer is grounded to the ground pattern. The present invention also provides a method for manufacturing the electronic component package. The electronic component package is excellent in the adhesion of the shield layer.
