1. A terminal structure comprising:

  • a flexible printed circuit board including an electrically insulative film on which a terminal area is defined at one portion thereof and a predetermined area is defined at another portion thereof adjacent said terminal portion, and an electric conductor pattern disposed on said film at said terminal area and at said predetermined area,said electrically insulative film comprising thermoplastic synthetic resin and said electric conductor pattern comprising solidified electrically conductive paste;

    an electrically insulative coating comprising a synthetic resin disposed on said electrically insulative film covering only the portion of the electric conductor pattern disposed at said predetermined area;

    metallic terminal members disposed over respective portions of said electric conductor pattern at said terminal area, said metallic terminal members also extending a predetermined distance from said terminal area;

    a terminal fixing film comprising an electrically insulative thermoplastic synthetic resin disposed at said terminal area over said metallic terminal members, said terminal fixing film fixing said metallic terminal members relative to said printed circuit board and over said respective portions of said electric conductor pattern; and

    fusion bonded portions at which said terminal fixing film is fusion bonded to said electrically insulative film of said printed circuit board being located at said terminal area adjacent locations at which said metallic terminal members are disposed over the respective portions said, electric conductor pattern.
