This application provides a battery cell, a battery, and an electric apparatus. The battery cell includes a housing, an electrode terminal, an electrode assembly, and a connecting component. The electrode terminal is provided on the housing, and the electrode assembly is accommodated in the housing. The connecting component is configured to connect the electrode terminal and the electrode assembly. The connecting component includes a first connecting portion for connecting the electrode terminal, where the first connecting portion includes a main body region and a thinned region, the thinned region having a smaller thickness than the main body region, and at least part of the thinned region being used for welding to the electrode terminal. Through provision of the thinned region, the thickness at the thinned region is reduced.
