Beschreibung
Zusammenfassung:	A cap plate is hermetically coupled to an open side of a prismatic case and provided with an electrode terminal. The cap plate includes a first part coupled and electrically connected to the electrode terminal. The first part includes a pressure deformation portion configured to deform toward the electrode terminal upon receiving a pressure. The cap plate includes a second part includes a first portion coupled to the pressure deformation portion of the first part, and a second portion coupled to an electrode lead of an electrode assembly.
