An aspect of the present invention provides an electromagnetic wave absorption film that is less susceptible to the surrounding environment.
An electromagnetic wave absorption film 10 has: a planar base 20; a first electromagnetic wave absorption pattern 1 formed on the base 20; a second electromagnetic wave absorption pattern 2 formed on the base 20; and a third electromagnetic wave absorption pattern 3 formed on the base 20, wherein when A [GHz] is defined as a frequency at which an absorption amount of an electromagnetic wave absorbed by the first electromagnetic wave absorption pattern 1 exhibits its local maximum value in a range from 20 to 110 GHz, B [GHz] satisfies Expression (1), B [GHz] being the value of a frequency at which an absorption amount of an electromagnetic wave absorbed by the second electromagnetic wave absorption pattern 2 exhibits its local maximum value, and C [GHz] satisfies Expression (2), C [GHz] being the value of a frequency at which an absorption amount of an electromagnetic wave absorbed by the third electromagnetic wave absorption pattern 3 exhibits its local maximum value, 1.037×A≤B≤1.30×A  Expression (1) 0.60×A≤C≤0.963×A  Expression (2).
