Abstract: An IC package has a substrate having recesses formed on the side wall thereof, an insulating film for covering an opening of each recess on the side of a principal surface of the substrate, and an IC chip mounted on a mount surface side of the film on the substrate, wherein a conductive portion formed on each recess is used as an external connection terminal for the IC chip. A method of assembling an IC package has the steps of forming a substrate having a plurality of through holes each having an insulating film covering one of the openings of each through hole, mounting one or more IC chips on a principal surface of the substrate on the insulating film side, and electrically connecting the IC chip and the through holes, sealing the substrate with the IC chip mounted thereon with insulating resin, and cut the substrate with the IC chip mounted thereon to expose the side wall of each through hole.
