The invention relates to a capacitor, in particular to a megavolt-level ceramic intermediate energy storage capacitor integrated with a voltage measurement function. The problems that an existing intermediate energy storage dry-type thin film capacitor is tedious in process, large in size and prone to being damaged, and the occupied space is large when a large resistor or a resistance-capacitance voltage divider is used for measuring high voltage are solved. The megavolt-level ceramic intermediate energy storage capacitor integrated with the voltage measurement function comprises a shell, N ceramic capacitor substrates and a voltage measurement device, wherein N is greater than or equal to 2; the N ceramic capacitor substrates are sequentially connected end to end to form a series structure, and the low-voltage side of the series structure is connected with a voltage measuring device; and the shell covers the series structure and a connecting metal layer, a small resistor and a resistor insulating layer in th
