Kind Code:
A1
Abstract:
This electronic device (100) is provided with: a first substrate (120) which has a wiring pattern formed therein; a second substrate (160) which has an external terminal formed thereon; first electronic equipment (141) which is disposed on a first surface of the first substrate; second electronic equipment (110) which is disposed on a second surface of the first substrate; a mold layer (130) for molding the first electronic equipment; and a conductive part (150) which is disposed inside the mold layer. The second electronic equipment is electrically connected to the first electronic equipment. The conductive part electrically connects the first substrate and the second substrate. The mold layer has, formed at an end thereof, a stepped part (170) where the conductive part is exposed. The second substrate is disposed at the stepped part. The distance in the thickness direction between the second substrate and the first substrate is shorter than the distance between the first surface of the first substrate and a surface of the first electronic equipment on the side opposite to the first substrate.
