しかしながら、上記した従来の包材を使用した
調理法では、包材に包まれた調理品が見えないう

包材を提供して、上記従来の問題点を解消するも
のである。
〔作用〕
本考案においては、調理品からの水蒸気を包装

〔実施例〕
本考案を以下、図示の実施例により具体的に説

が層状に重なつたシ−トAが形成されている(第
2図参照)。
上記シ−トAには、多数のスリツト5が、一方

リツトと交互になるように穿設され、このスリツ
トの配列方向と直行する方向に延伸可能となつた
シ−トAから電子レンジ調理用包材が形成されて
いるのであつて、第5図に示すように、調理品B
(例えば魚類)を包み一端部でシ−ト6すること
によつて、スリツト5それぞれが開き調理品Bの
形状に合つた状態で包装できる。そしてこの包装
された調理品Bを電子レンジにかけることによつ

焦げ具合が得られるとともに、網目状の焦げ目を
付けることができる。
また流通時においては、第6図に示すように、
電子レンジ調理用包材で包装した調理品B(第5
図参照)を外装袋Cに収納し、真空包装などによ
り緊縛した状態で包装すれば、シ−トAは調理品
Bと一層密着した状態に保持されることになり、
外装袋Cから取出し電子レンジにかける際、上記
効果をより向上させることができる。ここで外装
袋Cはポリプロピレンなどのプラスチツクフイル

よい。
また調理品Bとして「開き」状態の魚類を本考
案の包材で包み電子レンジにかける場合、開いた
魚類の両面をシ−トAで包んでもよいが、第8図
と第9図に示すように、開き魚(調理品B)を折
り合わせその折り合わせの間にシ−トAの一辺を
差し入れて巻き付ければ、シ−トAの使用面積が
小さくなるとともに、折り合わせた内面側にも焦
げ目を付けることができる。このときシ−トAは
ラベルで止めたり、或は全体をピロー脱気包装し
魚に密着させてもよい。
さらに魚の尾ひれなど調理品Bの一部が過剰に
加熱され焦げ付き易い場合は、第10図に示すよ
うに、所望の部分だけをシ−トAで包装すると調
理品Bの仕上げが美しくなる。
上記シ−トAは、基材4の一面に発熱体3を一

3図に示すように、基材4側に金属層2が位置す
るように基材4の両面に発熱体3を一体に設けて
もよく、また第4図に示すように、発熱体3を2
