Abstract: The present invention relates to a current sensing device comprising: a bus bar including a plurality of low-resistance metal portions separated from each other with a resistance portion therebetween; a printed circuit board arranged below the bus bar; a plurality of fixing pins which are joined to the metal portions of the bus bar to fix the bus bar on the printed circuit board and provide a current path between the metal portions and the printed circuit board; and at least one Hall sensor module. At least a portion of the Hall sensor module is inserted into a sensor hole formed in at least one of the low-resistance metal portions of the bus bar.
