PURPOSE:To attain a thin structure and to enable easy replacement of LSI, by contact-bonding the end portion of a flexible printed board with an LSI chip mounted thereon and the terminal portion of a main printed board so as to obtain an electric connection. CONSTITUTION:An LSI chip 7 is mounted on a flexible printed board 8. The other end of a conductor member 8a forms a folded portion at the end 8c of the flexible printed board 8 and is contact-bonded to a terminal portion 10 provided on a main printed board 9 whereon other main electric circuit components are arranged. Then, said end of the conductor member is fixed by a presser bar 11 and connected electrically to the terminal portion 10. By loosening the presser bar 11, the LSI chip 7 can be removed together with the flexible printed board 8, and thus easy replacement by a flexible printed board fixed with an LSI chip to be substituted is enabled. |
