An electron emitter has an electric field receiving member formed on a substrate, and a cathode electrode and an anode electrode formed on a same surface of the electric field receiving member. A slit is formed between the cathode electrode and the anode electrode. The cathode electrode is supplied with a drive signal from a pulse generation source, and the anode electrode is connected to an anode potential generation source (GND in this example). A collector electrode is provided above the electric field receiving member at a position facing the slit. The collector electrode is connected to a collector potential generation source (Vc in this example) through a resistor. The electric field receiving member is made of a piezoelectric material.
