  "textContent": "An electrochemical apparatus includes an electrode assembly and a conductive plate. The electrode assembly is of a wound structure and includes a first electrode plate. The first electrode plate includes a first conductive layer and a first conductive material layer. The first conductive layer includes a first surface and a second surface. The first conductive material layer is provided on the first surface. The first surface includes a first region. The conductive plate is connected to the first region and extends out of the first electrode plate. The conductive plate includes a third region and a fourth region connected to each other. The third region includes a connection region. The conductive plate is connected to the first region through the connection region. The third region includes a first side, a second side, a third side, and a fourth side. The first region includes a fifth side, a sixth side, and a seventh side. A size of the third region in the third direction is T, a size of the third region in the second direction is T, an area of the third region is S, an area of the connection region is S, a distance between the first side and the fifth side is J, a distance between the second side and the sixth side is J, and a distance between the third side and the seventh side is J, where S/S + (J + J + J)/(T + T) ≥ 30%. This application further provides an electronic apparatus.",
