Abstract
A trap for collecting solid is connected to either an exhaust port or a suction port of a vacuum pump for trapping a solid material separated from a sublimed gas discharged by the vacuum pump. The trap includes a casing, a passage defining member disposed in the casing and defining a gas passage in the casing, and an intermediate member disposed between the casing and the passage defining member. The intermediate member is made of a flat thin sheet which is formed into a tubular member, and the tubular member is capable of being spread when taken out from the casing.
