Abstract
A disclosed electronic device includes a graphite laminate having a plurality of layers laminated in a first direction, each layer containing graphite, where the graphite laminate has a portion in a stepwise form in which edges of the plurality of layers are offset from each other.
Claims9
An electronic device comprising:
- a graphite laminate having a plurality of layers laminated in a first direction, each layer containing graphite;
- a housing forming a heat radiation portion and configured to house the graphite laminate;
- and
- a heat source disposed within the housing,
- wherein the graphite laminate comprises:
- a first portion in a stepwise form in which first edges of the plurality of layers toward a second direction orthogonal to the first direction are offset from each other, the first portion being thermally connected to the heat source;
- and
- a second portion in a stepwise form in which second edges of the plurality of layers toward a third direction orthogonal to both the first direction and the second direction are offset from each other, the second portion being thermally connected to the heat radiation portion.

- and
- a heat source disposed within the housing,
- wherein the graphite laminate has a portion in a stepwise form in which edges of the plurality of layers are offset from each other,
- the portion is thermally connected to at least one of the heat source and the heat radiation portion, and forms the stepwise form in the first direction with respect to a corresponding one of the heat source and the heat radiation portion, and
- the portion includes
- a first portion forming an end portion of the graphite laminate toward a second direction orthogonal to the first direction and being thermally connected to the heat source, and
- a second portion forming an end portion of the graphite laminate toward a third direction orthogonal to the first direction at a position away from the first portion and thermally connected to the heat radiation portion.
