Abstract:
1. An electronic device, comprising: a semiconductor device; a heat-conductive resin, disposed above the semiconductor device and being in contact with a first surface of the semiconductor device, including heat conductors which are arranged in a direction orthogonal to the first surface and a resin with which gaps between the heat conductors is filled; a linear carbon piece disposed above the heat-conductive resin; and a heat spreader, disposed above the linear carbon piece, including a depressed portion having the resin, the linear carbon piece configured to be thermally in contact with the heat conductor at a second surface of the heat spreader facing the first surface of the semiconductor device, wherein the linear carbon piece is disposed so that a longitudinal side of the linear carbon piece is along with the second surface of the heat spreader.
