<p>A cooking stove in which heat exchange between combustion gas and the bottom surface of a cooking container is sufficiently conducted and heat exchange efficiency is improved is provided. On a top plate (2), a plate (7) that supports a cooking container P is arranged concentrically with the burner head (5) of the burner (4) viewed from above. This plate (7) is disc-shaped where an opening (8) which is larger than the burner head (5) is defined at the center. Moreover, eight protrusions (9, 9 ...) having an angular cross section where slopes become gentler as they extend toward the outer circumferential side are spirally arranged around the opening (8) viewed from above, and these protrusions (9) are formed by press forming.</p> |
