Abstract
A filler composition comprising fibrous basic magnesium sulfate particles and non-fibrous inorganic micro-particles having an average particle diameter in the range of 0.001 to 0.5 μm in a ratio by weight in the range of 100:0.001 to 100:50, and a polyolefin resin composition comprising a polyolefin resin, fibrous basic magnesium sulfate particles and non-fibrous inorganic micro-particles having an average particle diameter in the range of 0.001 to 0.5 μm, in which the polyolefin resin and fibrous basic magnesium sulfate particles are present in a weight ratio of 99:1 to 50:50, and the non-fibrous inorganic micro-particles are present in an amount of 0.001 to 50 weight parts per 100 weight parts of the basic fibrous magnesium sulfate particles and/or in an amount of 0.0002 to 10 weight parts, per 100 weight parts of the resin.
