<p><P>PROBLEM TO BE SOLVED: To provide a brush head excellent in hydrolyzability and capable of improving its rigidity. <P>SOLUTION: Sheets 10 made of a hydrolyzable material are overlapped to form a sheet laminated body. The sheet laminated body is compressed and bonded at a base end 3 that is detachably held by a handle. Each of the sheets 10 is formed by overlapping and bonding a flat base material sheet 11 and a solid sheet 12 whose cross-sectional shape is wavy, which allows each of the sheets 10 to employ a flute structure such as a cardboard to improve its hydrolyzability and rigidity. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
