A high dielectric-constant film is disclosed. The film may be comprised of one or more layers. At least one layer is comprised of a thermoplastic polymer having dispersed therein a ferroelectric substance having a dielectric-constant of at least 10. The ferroelectric substance is present in an amount of 5% to 80% by weight based on the weight of the entire film. The film provides a high dielectric-constant and can be produced easily and economically.
