I have examined in this thesis the form,material and finising of munafuda(dedication board) of Shinto shrines and Bud-dhist temples in the northern part of Kyushu and adjacent area.The outcome is as follows: The examination of the size (the total height,the thickness,the upper and under width,and the side height) of munafudahas shown that the size which "Daisho tekagami" dictated was not always observed,and that dedication boards were not necessarily made according to an auspicious scale. That is, the size of a dedication board was determined by the very length of the description sentence and the size of letters, and the space on which various dedication boards were attached.The forms of munafuda can roughly be classified into three types---sento style(a point-headed type), square style(a level-headed type)and ento style(a round-headed type). In each type,there are ones with their upper or lower corner cut off. This deliberate cutting-off of one of the corners was meat to turn the dedication board into an amulet. As for the finishing tools of munafuda, adzes and yariganna were used in the middle ages, but in the early modern age planes were common. The material of munafuda is generally wood obtained nearby. In the northern part of Kyushu and adjacent area, Japan ceder occupies about 55% of the all materials, followed by Japanese cypress, then nine, camohor, and zelkova.
