【０００２】
【従来の技術】樹脂複合体と加硫ゴムとを接合する方法
としては、所定形状に成形した樹脂複合体に接着剤を塗
布し、これに加硫ゴムを圧着し、何らかの方法で接着剤
を加熱、活性化して相互に接合するのが一般的である。
しかし外部からの加熱ではどうしても全体を接着剤の反
応温度以上に上げることになるため、有機物が主体の樹
脂複合体と加硫ゴムは熱による劣化や変形が懸念され
る。したがって、接着剤近傍だけを選択的に加熱できる
ような内部加熱方式を取らざるを得ない。
【０００３】例えば、特開平３−２２１４３４号公報に

着剤とともに挟んでＦＲＰ材料と加硫ゴムとを圧着さ
せ、この圧着部を高周波加熱法により発熱させて接合す

【発明が解決しようとする課題】接着強さの観点に立つ
と、接着層の厚みは極力薄い方が良い。これは接着層が
