実施の形態1では、内底面112において各溝114内にのみ凹凸構造30が形成されている場合を例示した。この実施の形態2では、外方領域にも凹凸構造が形成されていてもよい。つまり、(7)(1)~(6)のいずれか一項に記載の蒸気発生体であって、マーキング面において溝114の外方にも凹凸構造が形成されている。図6は、実施の形態2に係る内底面112aを示す平面図である。具体的には、図6は図3に対応する図である。図6に示すように、内底面112aにおいて各溝114a及び各外方領域115aには、それぞれ凹凸構造30a(図6においてドットハッチングで表現)が形成されている。
実施の形態1では、複数の溝114がストライプ状に形成されている場合を例示した。しかしながら、複数の溝のレイアウトは如何様でもよい。図7は、実施の形態3に係るベース部110bの上面図である。具体的には図7は図2に対応する図である。図7に示すように、実施の形態3に係る内底面112bには複数の溝114bが格子状に配置されていてもよい。
以上、本発明に係る蒸気発生体などについて、上記の実施の形態に基づいて説明したが、本発明は、上記の実施の形態に限定されるものではない。
