<P>PROBLEM TO BE SOLVED: To achieve stable manufacturing which gives easy visibility after coating by coating only necessary portions with an insulation coating material. <P>SOLUTION: A control apparatus has a printed circuit board 30 on which electronics parts are to be mounted, and a resin case to which the printed circuit board 10 is fixed. A groove 1 is formed on a bottom part inside the resin case 10 and the circumference of the groove 1 is in close contact with the printed circuit board 30. In the printed circuit board 30, two holes (4 and 5) are provided at portions requiring dampproofing, and one of the holes is taken as an insulation coat material-injecting opening 4 and the other thereof is formed so that the insulation coat material overflows after being filled in the groove, thereby preventing the injected insulation coat material from leaking from between the groove 1 and the printed circuit board 30. The one hole allows the insulation coat material to be injected therethrough and the other hole allows the overflowing of the insulation coat material into the formed resin groove to be visible, thereby eliminating variations in application amount and coating range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
