    摘要： A vacuum cleaner includes an electric air blower; a dust separator placed at an upstream side of the electric air blower and having a filtration filter for taking in dust-containing air sucked by the electric air blower and separating the dust from the air; and a dust accommodating section for accommodating the dust separated by the dust separator. The filtration filter includes a plurality of through-holes penetrating from an upstream surface at an upstream side to a downstream surface at the downstream side, and a central axis of the through-hole is inclined with respect to a normal line direction of a surface of the filtration filter.
