Abstract
An electromagnetic wave shielding film includes an electroconductive adhesive layer having high peel strength and high connection reliability and suppresses cracks in an insulating layer on the electroconductive adhesive layer. The electromagnetic wave shielding film includes an electroconductive adhesive layer containing electroconductive particles and an adhesive resin composition and an insulating layer on the electroconductive adhesive layer. The electroconductive particles include high melting point electroconductive particles and low melting point electroconductive particles having a lower melting point than the high melting point electroconductive particles, and the high melting point electroconductive particles include high melting point flaky particles and high melting point spherical particles, and the content of the high melting point flaky particles is 60 to 80% by weight of the total content of the high melting point flaky particles, the high melting point spherical particles, and the low melting point electroconductive particles.
