A producing method for the rectangular battery includes a step of impregnation examining to determining an impregnated state of the electrolytic solution in the electrode body by holding and pressing a first side wall portion and a second side wall portion of the rectangular battery to bring their inside surfaces into contact with an electrode body, bringing a transmitting probe and a receiving probe into close contact with the first side wall portion and the second side wall portion respectively, and in a state that an absorption member is placed to absorb diffused ultrasonic wave or going-around ultrasonic wave, transmitting the post-penetrated ultrasonic wave to pass through the electrode body and others, and receiving it by the receiving probe.",
