A coat-forming device (10) is provided with a distance measuring means for measuring the distance between a skin (S) and the coat-forming device (10), a distance determining means (31) for determining whether the distance measured by the distance measuring means (30) is an appropriate distance for electrostatic spraying, and a distance notifying means (32) for informing a user of the coat-forming device (10) about the determination results from the distance determining means (31). The coat-forming device 10 is a handheld-type device that is shaped and sized so as to be able to be held in the hands of a user. It is desirable to further provide an angle measuring means (42) for measuring the angle formed by the direction of the electrostatic spray and the skin on which the coat is to be formed.本發明之被覆膜形成裝置(10)具備:測距機構(30),其測定皮膚(S)與被覆膜形成裝置(10)之距離;距離判定機構(31),其判定由測距機構(30)所測定之距離是否成為適合於靜電噴塗法之距離;及距離通知機構(32),其將距離判定機構(31)之判定結果通知給被覆膜形成裝置(10)之使用者。被覆膜形成裝置(10)係具有由其使用者利用手便能夠保持之形狀或大小之手持型者。較佳為進而具備角度測定機構(42),其測定靜電噴塗之方向、與欲形成被覆膜之皮膚所成之角度。10‧‧‧靜電噴塗裝置11‧‧‧低電壓電源12‧‧‧高電壓電源13‧‧‧輔助電路14‧‧‧微齒輪泵15‧‧‧組合物收納用容器16‧‧‧噴嘴17‧‧‧管路18‧‧‧軟性管路19‧‧‧電流限制電阻30‧‧‧測距機構31‧‧‧距離判定機構31H‧‧‧輸入及記憶機構31L‧‧‧輸入及記憶機構32‧‧‧距離通知機構33‧‧‧距離顯示器33a‧‧‧驅動電路33b‧‧‧LED陣列34‧‧‧警報機構C‧‧‧中央區域S‧‧‧皮膚S1‧‧‧側部區域S2‧‧‧側部區域SW‧‧‧開關
