Abstract
The invention aims to provide a protector that is prevented from being loosened from an electrochemical element, prevented from having dispersion in dimension and prevented from coming off the electrochemical element. In a protector 200 of an electrochemical element 100, that entirely covers an electrochemical element entirely covered with an aluminum laminate film 90, improvement is that the protector 200 has a recess 210, 220 that receives a wrinkled portion 92 of the aluminum laminate film 90, the wrinkled portion 92 being formed at a corner portion of the electrochemical element 100. Thus, when it is intended to mount the protector 200 to the electrochemical element 100, the wrinkled portion 92 of the aluminum laminate film 90 is received into the recess 210, 220 that is to say, the recess 210, 220 serves as a relief for the wrinkled portion 92. Thus, the protector 200 can be intimately connected to the electrochemical element 100.
