Dear Haruo,
This is a species of Hancockia which I am pretty sure is unnamed. From its name, I guess the Eckloniopsis radicosa you found it on is a brown alga. Species of Hancockia are often found on laminarian brown algae and kelp, because the strong flattened 'leaves' are a good place for hydroids, which Hancockia feeds on, to grow.
Best wishes,
Bill Rudman
