Chrysanthemum-shaped element and method for manufacturing the same, filter body and fluid filter

A chrysanthemum-shaped element in a cylindrical shape in which folds are formed and inner surfaces of adjacent folds are bonded at a top edge and a bottom edge thereof, said chrysanthemum-shaped element comprising:

• (A) an element body composed of a filter medium;
• said filter medium comprising:
• a filter paper;
• and
• a low-melting fiber layer formed on a surface of said filter paper on the inner surface side of said folds at least at said top edge and said bottom edge of said filter paper;
• and
• (B) bonding sections formed at said top and bottom edges on the inner surfaces of said folds by heat-adhesion of said low-melting fiber layer;
• wherein said low-melting fiber layer is formed of at least one of a fiber of a lower melting point than that of a filter paper material with which said filter paper is formed and compound fibers containing a fiber of a lower melting point than that of said filter paper material.
