To suppress local heat generation in a retainer.SOLUTION: A retainer includes: a plate-like member having a first surface orthogonal in a first direction; an internal electrode arranged inside the plate-like member; a terminal member arranged to the plate-like member, the terminal member being capable of conducting electricity to the internal electrode; a terminal-side electrode exposed from the first surface of the plate-like member, the terminal-side electrode being connected to the terminal member; a plurality of first via conductors arranged inside the plate-like member, each first via conductor extending in the first direction to be connected to the terminal-side electrode; and a conductive connection electrode connected to the first via conductor, the conductive connection electrode being electrically connected to the internal electrode. In the retainer, the plurality of first via conductors are arranged side by side in a third direction that intersects a second direction in which current flows through the connection electrode when the current is flown between the terminal member and the internal electrode.SELECTED DRAWING: Figure 5 【課題】保持装置における局所的な発熱を抑制する。【解決手段】第１の方向に直交する第１の表面を有する板状部材と、前記板状部材の内部に配された内部電極と、前記板状部材に配され、前記内部電極に通電可能な端子部材と、前記板状部材の前記第１の表面から露出し、前記端子部材に接続される端子側電極と、前記板状部材の内部に配され、前記第１の方向に延在して前記端子側電極に接続される複数の第１ビア導体と、前記第１ビア導体に接続され、前記内部電極に電気的に接続される導電性の接続電極と、を備える保持装置において、複数の前記第１ビア導体を、前記端子部材と前記内部電極との間に電流が流されたときに当該電流が前記接続電極中を流れる第２の方向に交差する第３の方向に並ぶように配置する。【選択図】図５
