摘要： A current interruption device includes: a deforming plate configured to deform when the internal pressure of the casing rises above the predetermined level; a conducting plate which configures the current path; and a contact plate. The conducting plate includes a first contact portion configured to contact the contact plate. The contact plate includes a second contact portion configured to contact the first contact portion. The deforming plate includes a pressure receiving portion configured to receive the internal pressure of the casing and a contacting portion configured to contact the first contact portion. The second contact portion is configured to be separated from the conducting plate by deformation causing the contacting portion to move toward the contact plate. The deforming plate is insulated from the conducting plate and the contact plate. The conducting plate is disposed to be interleaved between the deforming plate and the contact plate.
