PROBLEM TO BE SOLVED: To provide a laminated sealable material which is best-suited for use as a lid material for a container made of glass, paper or plastics, and can be sealed by high-frequency induction heating. SOLUTION: This high-frequency sealable laminate is constituted of a potassium ionomer of an ethylene-unsaturated carboxylic acid copolymer or a mixture of the potassium ionomer and a thermoplastic resin. In addition, the laminate is constituted of a layer (A) showing the product of a dielectric constant and a dielectric dissipation factor of not less than 0.07 at a frequency of 13.56 MHz, a sealing layer (B) and a base layer (C) formed on the layer (A) depending on occasion.
