Abstract
A cooling structure includes: a main body including a base, and heat dissipation fins and a protrusion that protrude from a heat dissipation surface; a lid member disposed to cover the protrusion and the fins and form a flow path; and a fan mechanism. The fan mechanism includes a vane portion, a driving portion that rotates the vane portion, and a conductive wire for supplying electric power to the driving portion. The protrusion includes a first through hole, and the base includes a second through hole communicating with the first through hole. The conductive wire includes a first portion connected to the driving portion and disposed between the lid member and the main body, and a second portion continuing from the first portion and inserted in the first through hole and the second through hole. The cooling structure enables enhancement of the heat dissipation and shielding performance.
