1. A portable electronic device, comprising:
a housing that includes:
a pair of main surface portions, wherein
a first main surface portion of the pair of main surface portions includes a support portion that supports a display panel;
a chassis member that includes a recessed portion;
a first heat generating element;
an antenna module in a vicinity of an inner surface of the housing, wherein a gap is present between the antenna module and the inner surface of the housing;
a first heat diffusion member in the housing, wherein
the first heat diffusion member is separated from the inner surface of the housing,
the first heat diffusion member is thermally connected to the antenna module, and
a path through which heat generated by the antenna module is transferred along the first heat diffusion member is separated from the inner surface of the housing; and
a third heat diffusion member in the recessed portion of the chassis member, wherein
the third heat diffusion member is in thermal contact with an inner surface of the recessed portion,
the third heat diffusion member is separated from the inner surface of the housing, and
heat generated by the first heat generating element is transferred to the third heat diffusion member via the support portion of the chassis member.
