摘要： {Problem} To provide a polyolefin resin composite material in which the size of cellulose aggregates is sufficiently small, and in which a polyolefin resin and cellulose are integrated with high uniformity.
{Means} A polyolefin resin composite material, comprising: a polyolefin resin; and 10 to 150 parts by mass of cellulose fibers with respect to 100 parts by mass of the polyolefin resin, wherein an area of aggregates of the cellulose fibers is less than 20,000 µm 2 ; and a method of producing the same.

摘要： A core portion; and a cladding portion positioned around a periphery of the core portion and having holes arranged circularly around the core portion are included. Twelve to thirty-six of the holes are arranged circularly at a radius of 36 to 48 micrometers around an approximate center of the core portion, a hole diameter is in a range of 2.0 to 11.0 micrometers, and at a wavelength of 1064 nanometers, a single-mode operation is substantially performed and an effective core area is equal to or greater than 1500 µm 2 . Accordingly, a holey fiber is provided, which is capable of propagating light in a form preferable for practical uses while achieving a substantial single-mode operation and low nonlinearity.
