Claim Text:
1. A method of manufacturing an electronic component module, comprising: a first step of sealing a surface of an aggregate substrate on which a plurality of electronic components are mounted with a sealing resin; a second step of cutting a boundary portion between electronic component modules from an outer surface of the sealing resin to a position where the aggregate substrate is cut at least partially through and forming a first groove; a third step of forming a shield layer by coating the outer surface of the sealing resin with a conductive resin and by filling the first groove with the conductive resin; a fourth step of forming a conductive resin projection at a position on the shield layer where the first groove is formed and forming a recess at a position where the conductive resin projection is formed; and a fifth step of cutting the boundary portion between the electronic component modules along the recess from an outer surface side of the shield layer to the position where the aggregate substrate is cut at least partially through, forming a second groove having a width smaller than the width of the recess, and singulating the aggregate substrate into the individual electronic component modules, wherein, in the second step, the boundary portion is cut between electronic component modules from an outer surface of the sealing resin to a position where the aggregate substrate is completely cut through.
