1. A resin composition, comprising:
a hydrophilic resin and a metal compound, the metal compound being a lamellar metal compound represented by the following chemical formula (4):
Ma(OH)bAn-(2a-b)/n  (4)
wherein:
M is a metal species,
A is ROCO,
R is an alkyl chain represented by a chemical formula CmH2m+1 where m=1 to 20 and optionally has a functional group,
n is an integer not less than 1, and
a and b are numbers greater than zero and satisfy an expression a/b=0.1 to 10, and satisfying the following expression (1) when being formed into a film:
α1−β1≥1  (1)
wherein:
α1 is an average metal atom concentration (%) in a portion of the film in a depth range of 0 to 9 nm from a film surface, and
β1 is an average metal atom concentration (%) in a portion of the film in a depth range of 12 to 21 nm from the film surface.
