ELECTROCHEMICAL DEVICE AND ELECTRONIC DEVICE

An electrochemical apparatus (1) and an electronic apparatus are disclosed. The electrochemical apparatus (1) includes an electrode plate (10) and a tab (20), where the electrode plate (10) includes a current collector (11), a first active material layer (12), and a first insulation layer (13). The current collector (11) includes a first region (Z1), a second region (Z2), and a first portion of a third region (Z3), where the first region (Z1) is provided with the first active material layer (12), and the second region (Z2) is provided with the first insulation layer (13). Along a thickness direction of the current collector (11), an orthographic projection of the second region (Z2) at least partially surrounds an orthographic projection of the first portion of the third region (Z3). In this way, the electrode plate (10) has a small exposed conductive region. This can reduce the safety risk such as a short circuit risk caused during a needle penetration operation on the electrochemical apparatus (1).
