<p><P>PROBLEM TO BE SOLVED: To provide an insulating compact with a stable electric characteristic in a simple manufacturing method. <P>SOLUTION: The insulating compact 1a has a cylindrical insulating tube 11a including an insulating rubber, and an internally semiconductive layer 12a including a semiconductive rubber provided in the inner periphery of the insulating tube 11a. A semiconductive layer 18a is formed as including the coated layer of a semiconductive coating material at the external side of the internally semiconductive layer 12a. Further, an R section 122a is formed on the end of the internal semiconductive layer 12a, and the coated layer 18a is formed from the flat surface 123a of the internally semiconductive layer 12a across the R section 122a. At this case, the coated layer 18a is preferably formed from the flat surface 123a of the internal semiconductive layer 12a through the R section 122a across the internal surface close to the end of the internally semiconductive layer 12a. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
