To provide a battery temperature adjustment device capable of uniformly adjusting a temperature with respect to a plurality of battery cells without involving an increase in size, and to provide a battery device.SOLUTION: A battery temperature adjustment device comprises a battery case 30 which can house a battery cell 21 between side wall parts 31 in a laminated condition. One of the side wall parts 31 comprise a first medium flow path Fa, and the other one comprises a second medium flow path Fb. The battery case 30 includes: a first communication path f4 communicated with one end part of the first medium flow path Fa and one end part of the second medium flow path Fb; and a second communication path f5 communicated with the other end part of the first medium flow path Fa and the second medium flow path Fb. A temperature adjustment medium is introduced to the first medium flow path Fa and the second medium flow path Fb via the first communication path f4 or the second communication path f5 in parallel, is flowed into the second communication path f5 or the first communication path f4 from the first medium flow path Fa and the second medium flow path Fb, and is exhausted to an external part of the battery case 30. The first communication path f4 and the second communication path f5 are provided in parallel to a bottom face of the device.SELECTED DRAWING: Figure 1 【課題】大型化を招くことなく、複数のバッテリセルに対して均一な温調を行うことのできるバッテリ温調装置及びバッテリ装置を提供すること。【解決手段】側壁部３１間にバッテリセル２１を積層状態で収納可能なバッテリケース３０を備え、側壁部３１の一方に第１媒体流路Ｆａ、他方に第２媒体流路Ｆｂが設けられる。バッテリケース３０は、第１媒体流路Ｆａ及び第２媒体流路Ｆｂの一方端部に連通する第１連通路ｆ４と、第１媒体流路Ｆａ及び第２媒体流路Ｆｂの他方端部に連通する第２連通路ｆ５とを有し、温調媒体は第１連通路ｆ４又は第２連通路ｆ５を介して第１媒体流路Ｆａと第２媒体流路Ｆｂとに並行して導入され、第１媒体流路Ｆａ及び第２媒体流路Ｆｂから第２連通路ｆ５又は第１連通路ｆ４に流入し、バッテリケース３０の外部に排出されるように構成される。第１連通路ｆ４及び第２連通路ｆ５は、装置底面に並列して設けられる。【選択図】図１
