To solve the problem in which when the posture of a projector is changed, a relative positional relation between a refrigerant generation unit and an object to be cooled is changed, which may make it difficult to transmit a refrigerant to the object to be cooled.SOLUTION: A projector comprises a cooling device that cools an object to be cooled through a change of a refrigerant to gas. The cooling device has a refrigerant generation unit 20 that generates a refrigerant, and a refrigerant transmission unit 50 that transmits the generated refrigerant toward the object to be cooled. The refrigerant generation unit has an accumulation unit 31 in which the generated refrigerant is accumulated. The refrigerant transmission unit has a first channel unit 51 and a second channel unit 52 extending from the accumulation unit, and a power unit 55 that can cause the refrigerant in the accumulation unit to flow into the first channel unit and into the second channel unit. The accumulation unit has a first delivery port 36a to which the first channel unit is connected, and a second delivery port 36b to which the second channel unit is connected. The accumulation unit is provided therein a connection and transmission unit that connects the first delivery port and the second delivery port with each other and can transmit the refrigerant in the accumulation unit between the first delivery port and the second delivery port.SELECTED DRAWING: Figure 2 【課題】プロジェクターの姿勢が変化した場合等に、冷媒生成部と冷却対象との相対位置関係が変化し、冷却対象まで冷媒を伝送しにくくなる虞があった。【解決手段】プロジェクターは、冷媒が気体へ変化することで冷却対象を冷却する冷却装置を備える。冷却装置は、冷媒を生成する冷媒生成部２０と、生成された冷媒を冷却対象に向けて伝送する冷媒伝送部５０と、を有する。冷媒生成部は、生成された冷媒が貯留される貯留部３１を有する。冷媒伝送部は、貯留部から延びる第１流路部５１および第２流路部５２と、貯留部内の冷媒を第１流路部内および第２流路部内に流すことが可能な動力部５５と、を有する。貯留部は、第１流路部が接続された第１送出口３６ａと、第２流路部が接続された第２送出口３６ｂと、を有する。貯留部の内部には、第１送出口と第２送出口とを繋ぎ、貯留部内の冷媒を第１送出口と第２送出口との間で伝送可能な接続伝送部が設けられている。【選択図】図２
