The present invention is to provide an electronic component where positional accuracy for arranging members constituting a circuit element such as a resistor element and the like is mitigated and corrosion of a terminal electrode caused by sulfur in the atmosphere is reduced. The four chips connected resistor device 1 as an electronic component comprises: an insulating substrate 2 including a front surface 2a, a back surface 2b and a side surface 2c connecting the front surface 2a with the back surface 2b; a pair of terminal electrodes placed on the front and back surfaces 2a and 2b and the side surface 2c; a resistor element 5 including a resistor member 4 connected to the pair of terminal electrodes, and a protective layer (a glass film 6 and an overcoating film 7) for protecting the resistor member 4: the auxiliary electrode 9 placed with covering the interface 8 between the overcoating film 7 and the terminal electrode 3; and a nickel plated layer 10 and a solder plated layer 11 placed on the surfaces of the terminal electrode 3 and the auxiliary electrode 9. The interface 8 is placed at the end portion 2c of the insulating substrate 2.
