Abstract
The invention provides novel pellets having high fluidity in a hopper of an extruder and capable of forming a coating layer having good wire diameter stability and capacitance stability even when used for rapid molding of electric wire coating. The pellets contain a fluororesin. Each of the pellets, placed on a horizontal surface, has a substantially circular outline or a substantially elliptic outline and has a major axis D1 of 3.1 mm or shorter and a minor axis D2 of 3.1 mm or shorter when observed in the direction normal to the horizontal surface. Each pellet satisfies the following formula (1): (D1+D2)/2L=1.8 to 2.6, wherein D1 represents the major axis, D2 represents the minor axis, and L represents the height from the horizontal surface to the highest point of the pellet.
