PURPOSE:To accurately detect a residual amount of a paste corresponding to a pressure-raising duration by a method wherein a pressure gauge to detect a pressure at a space part inside a paste container is installed and the residual amount of the paste inside the paste container is detected from a length of the pressure-raising duration from a starting point to feed a compressed gas to a point when the pressure gauge detects an arbitrarily set pressure. CONSTITUTION:When a residual amount of a paste inside a paste container 11 is much, a volume of a space part inside the paste container 11 is little; when a compressed gas is fed to the space part, a pressure-raising duration t1 during which a pressure Px at a space part reaches a preset pressure Pa is comparatively short. On the other hand, when the residual amount of the paste inside the paste container 11 is little, the volume at the space part inside the paste container 11 is much; a pressure-raising duration t2 becomes comparatively long. Accordingly, if a pressure-raising duration(t) is counted, the residual amount of the paste corresponding to the pressure-raising duration(t) can be detected accurately.
