Zusammenfassung:To provide a vapor chamber which enables improvement of cooling efficiency, and to provide an electronic device including the vapor chamber.SOLUTION: A vapor chamber includes: a first metal plate; a second metal plate which is joined at an outer edge to the first metal plate and forms a sealed space, into which a working fluid is enclosed, with the first metal plate; and a wick housed in the sealed space. The first metal plate is formed with through holes communicating with the sealed space. The vapor chamber includes metal blocks each of which is inserted into the through hole and joined to the first metal plate to seal the through hole, each metal block including a flat outer surface provided at the opposite side of the sealed space side.SELECTED DRAWING: Figure 3 【課題】冷却効率を向上することができるベーパーチャンバ及び該ベーパーチャンバを備える電子機器を提供する。【解決手段】ベーパーチャンバは、第１金属プレートと、外縁部が前記第１金属プレートと接合され、前記第１金属プレートとの間に作動流体が封入される密閉空間を形成する第２金属プレートと、前記密閉空間に収容されるウィック、を備え、前記第１金属プレートは、前記密閉空間に連通する貫通孔が形成され、さらに、前記貫通孔に挿入されて前記第１金属プレートと接合されることで前記貫通孔を封止すると共に、前記密閉空間側とは逆側にフラットな外面が設けられた金属ブロックを備える。【選択図】図３
