PROBLEM TO BE SOLVED: To provide an ultrasonic welding inspection apparatus capable of inspecting an ultrasonically-welded state, without having to applying a force to an electrode tab. SOLUTION: The ultrasonic-welding inspection apparatus comprises a temperature measuring means 200 for measuring temperature distributions of ultrasonically welded workpieces 900a and 900b and a computation means 300 for computing ultrasonically welded regions of the workpieces 900a and 900b, through the use of temperature differences between an unjointed region and an ultrasonically jointed region of the workpieces 900a and 900b, of which the temperature distributions have been measured.
