Abstract
An adhesive film including a substrate film and an adhesive agent layer formed thereon is adhered to the back surface side of a mounting region of a flexible substrate, and an electronic component is mounted on the front surface side. An adhesive agent in the adhesive agent layer contains silica fine particles having a primary particle diameter of less than 100 nm, and the adhesive agent layer has a shear storage elastic modulus at 160° C. of 0.15 MPa or more. When the anisotropic conductive film is disposed on the mounting region and the electronic component is mounted on the anisotropic conductive film by heating and pressing, the adhesive agent is not pushed out to a large extent, and conductive particles sandwiched between a bump on the electronic component and the electrode are pressed and squashed, improving an electrical connection between the electronic component and the electrode.
