The invention provides a chip-type electric double layer capacitor cell and a method of manufacturing the same. The chip-type electric double layer capacitor comprises: a resin case having a housing space provided therein and formed of insulating resin and first and second external terminals inserted into the resin case by insert injection molding. Each of the external terminals has a first portion exposed to an outer surface of the resin case for external contact and a second portion exposed to an inner surface of the housing space for internal contact. a sealing portion includes a groove portion provided in the resin case along a circumference of at least one of the first and second external terminals and a resin filling the groove portion. An electric double layer capacitor cell is mounted in the housing space and electrically connected to the second portion of the first and second external terminals.
