PROBLEM TO BE SOLVED: To provide a printed circuit substrate which can be diagnosed for the deterioration of the soldered part of a circuit component mounted on the printed circuit board, without the need for special knowledge or special apparatus for diagnosing the deterioration of the soldered part, and to provide an electronic apparatus. SOLUTION: The printed circuit substrate 10 has a resistor 1 mounted as a dummy component which does not affect an influence to the circuit operation of the circuit component by soldering the circuit component, in such a manner that stress applied to the soldered part of the resistor 1 is set to more stringent conditions than the stress which is applied to the soldered part of the circuit component.
