Abstract
Abstract A network-type resistor array in which a plurality of resistors are successively arranged, in which electrode portions of the resistors are respectively separated by angular electrode-separating notches, so as to prevent the short-circuit between the adjacent electrode portions due to the flowing along of molten solder for electrode connection.
