    • An electronic device (100) includes a housing (10), a first electrocardiograph (ECG) electrode (20), a second ECG electrode (30), an ECG circuit board (40), and a conductive resilient sheet (50). The housing (10) includes a back cover (11) and a middle frame (12) fixed with the back cover (11). The first ECG electrode (20) is disposed at the back cover (11). The second ECG electrode (30) is disposed at the middle frame (12). The ECG circuit board (40) is disposed inside the back cover (11) and inside the middle frame (12), and provided with a first branch (41) electrically connected with the first ECG electrode (20) and a second branch (42) disposed adjacent to and extending toward the second ECG electrode (30). The conductive resilient sheet (50) is fixed inside the middle frame (12) and configured to make the second ECG electrode (30) and the second branch (42) be in a conducting state. The conductive resilient sheet (50) is provided to make the second ECG electrode (30) and the second branch (42) be in a conducting state, so that a closed path between the first ECG electrode (20) and the second ECG electrode (30) is shortened, thereby improving a sensitivity of obtaining ECG data and user experience.
