Abstract
A chip-type surge absorber and method for producing same, wherein the chip-type surge absorber includes an insulating substrate in the shape of a rectangular parallelepiped; an insulating hermetic cap open at a bottom side thereof, for forming, together with the insulating substrate, a box-shaped hermetically sealed cavity filled with a discharge gas; terminal electrodes disposed at both ends in the hermetically sealed cavity; a pair of discharge electrodes which are formed in the hermetically sealed cavity such that a discharge gap is formed between the discharge electrodes and such that the discharge electrodes are electrically connected to corresponding terminal electrodes; and connection surfaces for increasing the connection area for the connection between the discharge electrodes and the terminal electrodes.
