摘要： Provided is a cell assembly. The cell assembly includes a case configured to define an accommodation space, a battery cell accommodated in the accommodation space, a cover configured to define an installation space therein and installed on the case, and an element member disposed in the installation space and spaced apart from a wall of the cover that defines the installation space so as to be installed on the board, thereby safely protecting the element member therein. In addition, the cell assembly includes a support member disposed at a position higher than the element member to protect the element member against an external impact, and also, the board having a hole at a center thereof is applied so that a meal plate is exposed to a bottom surface through the hole so as to be connected to the battery cell.
