• in General Formula (1),
• p is in a range of 2 to 9,
• q is in a range of 1 to 8,
• p+q is an integer in a range of 3 to 10,
• Z represents a (p+q)-valent organic group,
• R1 and R2 each independently represent a single bond or a divalent organic group,
• A1 represents a monovalent group including one or more groups selected from the group consisting of an acidic group, a basic group having a nitrogen atom, a urea group, a urethane group, a group having a coordinating oxygen atom, a hydrocarbon group having 4 or more carbon atoms, an alkoxysilyl group, an epoxy group, an isocyanate group, and a hydroxy group,
• p pieces of A1's and p pieces of R1's may be each independently the same as or different from each other,
• P1 represents a polymer structure including a partial structure represented by General Formula (2), and
