PROBLEM TO BE SOLVED: To solve a problem of making a mess of a nail state in some cases due to failing to determine the degree of dislocation from a reference value after adjustment because of difficulty in judging whether the nail state is appropriate or not by making adjustments many times in the case that a clerk in a pachinko parlor adjusts nails of a pachinko board in the absence of a skilled person called a nail specialist although the nail adjustment made by the nail specialist is considered as an appropriate adjustment. SOLUTION: This nail position confirmation method for the pachinko board is provided for making an appropriate adjustment in the case that the clerk in the pachinko parlor adjusts the nails. As a concrete means, in the pachinko board with a pachinko ball passage formed between a plurality of nails erected on a base, the position of the head of the nail after adjusted is photographed from the front face of the pachinko board and put over a reference mark indicating the reference position of the nail, to discriminate the dislocation of the nail head after adjusted, from the reference mark.
