PROBLEM TO BE SOLVED: To provide an easily dryable antifouling member having excellent long-term durability. SOLUTION: This antifouling member has a base material composed of a material having the surface having <90 deg. contact angle with water as a flat surface, and having a groove shape with straightly successive mountains and valleys, regulated so that the cross section has many successive triangle shapes 1 arranged in parallel. One of the triangle shape 1 has the base with <=5,000 μm length, and 1.1-2.6 ratio of the sum of two sides except the base to the length of the base. As a result, the member has an excellent long-term durability and appearance, accelerates the drying, and simultaneously reduces the attachment of scales by preventing the partial cohesion of water and making the formation of a large droplet having >=5 mm diameter difficult by devising the surface shape of the base material itself without depending on a film and aftertreatment. |
