Disclosed is a fire extinguisher (100) comprising a fire extinguisher cylinder (10) for a fire-extinguishing agent. The fire extinguisher cylinder (10) comprises a mouth portion as an opening, a shoulder, a cylindrical body portion, and a bottom portion and is shaped with use of a resin provided with no joint. In addition, the body portion in the fire extinguisher cylinder (10) has a thickness from 1 mm to 5 mm, and a crystallinity of the resin is from 13% to 30% at the sites other than the mouth portion and the bottom portion.
