In order to obtain a switchgear which can improve heat dissipation efficiency, in the switchgear which dissipates heat outside an apparatus vessel, the heat being generated from an electrical apparatus placed in the apparatus vessel, the switchgear includes a first heat conductor in which one side is connected to a heat generation portion of the apparatus vessel and the other side is extended toward the apparatus vessel side, a second heat conductor in which one side is disposed near the other side of the first heat conductor and the other side is extended outside the apparatus vessel, and an insulating member between conductors disposed between the other side of the first heat conductor and one side of the second heat conductor.
