Abstract
In a cleaving apparatus for a glass film, an initial crack, which is formed at a leading end portion of a preset cleaving line of a glass film, is propagated along the preset cleaving line by a thermal stress generated in the glass film through localized heating performed along the preset cleaving line and cooling of a heated region resulting from the localized heating. At this time, a resin sheet having higher flexibility than the glass film is arranged in a cleaving region, and the resin sheet is floated by blowing a gas on a lower surface of the resin sheet by a floating unit. Then, a preset cleaving portion of the glass film including the preset cleaving line is lifted and supported while being covered with the floated resin sheet from below, and in this state, the glass film is cleaved.
