Claim 0:
1. A method for drying polyolefin-containing particles, the method comprising a drying step of supplying polyolefin-containing particles to a drying container, supplying a drying gas to the drying container, and drying the polyolefin-containing particles in the drying container, wherein

38.0×[η]CXIS[dL/g]−0.500×CXIS content[% by mass]+1.20×particle temperature during drying[K]+3.29×drying time[hr]  Formula (a):

wherein in formula (a),
CXIS means cold xylene insoluble,
[η]CXIS represents a limiting viscosity of a CXIS component in the polyolefin-containing particles, and
the CXIS content represents a content of a CXIS component in the polyolefin-containing particles.
