摘要： An electrostatic protection component includes: a body in which a plurality of ceramic substrates is laminated; and a pair of discharge electrodes which are formed within the body and which are spaced to face each other. The discharge electrodes include main body portions extending along a longitudinal direction, and the main body portions include tips in the longitudinal direction and side edges extending along the longitudinal direction. The pair of discharge electrodes are arranged such that both the main body portions are adjacent to each other in a short direction. The discharge electrodes face each other in the short direction between the side edges, and discharge occurs only between the side edges, between the discharge electrodes.
