摘要： A pair of electrodes are provided through a base. A cap and the base constitute a chamber, and are connected to each other by fitting projections provided on the base, into locking grooves formed in the cap. A fuse element is connected to upper portions of the electrodes, located in the chamber, by appropriate means such as soldering or welding. The base is in the form of a rectangle having long sides and short sides. A pair of semi-elliptic air pass holes are formed in substantially central portions of the base along the respective long sides, and opposed to each other.
