<P>PROBLEM TO BE SOLVED: To provide a sealing member used for, for example, an electronic component transfer case, which is excellent in retention of an antistatic function, is free of adverse effect on electronic components, etc., and is excellent in rubber elasticity which has freedom in coloring. <P>SOLUTION: The sealing member comprises a thermoplastic resin composition including (a) thermoplastic elastomer consisting of carbon atoms and hydrogen atoms and (b) a block polymer having a structure in which polyolefine blocks and hydrophilic group polymer blocks are bonded alternately. In the thermoplastic resin composition, the weight ratio (a):(b)=100:(2 to 100), JIS K6253 type A durometer hardness is 90 or less, and a volume resistivity value is 1×10<SP>12</SP>or less. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
