An ESD protection device 1 has a ceramic insulating material 10, first and second discharge electrodes 21 and 22, and a discharge-assisting section 51. The first and second discharge electrodes 21 and 22 are disposed somewhere of the ceramic insulating material 10. The discharge-assisting section 51 is located between the distal end portion of the first discharge electrode 21 and the distal end portion of the second discharge electrode 22. The discharge-assisting section 51 is an electrode configured to reduce the discharge starting voltage between the first discharge electrode 21 and the second discharge electrode 22. The discharge-assisting section 51 is made from a sintered body containing conductive particles and at least one of semiconductor particles and insulating particles. The first and second discharge electrodes contain at least one of the semiconductor material constituting the semiconductor particles and the insulating material constituting the insulating particles.
