The invention describes a centrally perforated ring-shaped ceramic capacitor belonging to the technical field of sensors. It is formed by the combined sintering of a ceramic base (1) and a ceramic reaction membrane (2). A hole (3) is provided in the axis of the ceramic base (1) and the ceramic reaction membrane (2) to provide an assembly passage for the circuit components to be assembled, allowing the ring-shaped capacitor to be more easily integrated into the complex circuit of the temperature and pressure sensor.
