The present invention provides a drum container for body fluid processor and a body fluid processor. Said drum container is that the strength nearby the thermoweld line is reduced less even though it is shaped by injection of plastic material with low impact resistance, and it is not easy to burst even though knocking using a nipper when pre-injecting operation, that is the drum container has high impact resistance. The drum container is shaped by injecting plastic material with less than 10 kg*cm/cm of impact resistance using a mould of a gas exhaust part by means of a mould part connecting to the position of thermoweld line of shaped production.
