Filler disposition film

A filler disposition film in which a prescribed filler is regularly disposed in a long resin film, wherein

• a rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more an average particle diameter of the filler, and a width of 0.2 mm or greater is 90% or greater,
• wherein the filler disposition film has a location at which the filler is not present and the location forms a filler omission, the filler disposition film has an area in which an omission is present with respect to the original disposition of the filler, a non-disposition area in which omissions are converged with respect to the original disposition of the filler, or an area in which the disposition differs from the original disposition of the filler,
• wherein the filler disposition film is wound onto a winding core to form a film wound body,
• wherein a film length of the filler disposition film is 5 m or more, and
• wherein the rate of consistency of disposition of the filler is a ratio of the number of overlapped prescribed fillers to the total number of fillers in both areas in a case in which both rectangular areas are made to overlap such that the number of fillers for which the center position overlaps is maximized, the center position is considered to be a circular area of prescribed diameter that is not more than 25% of the average particle diameter of the filler, and overlap of this type of filler can be determined by capturing images of both rectangular areas, and then overlapping the images through image processing.
