A film-like adhesive agent of one embodiment contains an acrylic resin (a), an epoxy compound (b1), and a phosphorus antioxidant (z). Before being heated at 260°C, this film-like adhesive agent has a linear transmittance of 90% or greater for light at a wavelength of 400 to 800 nm. After being heated for ten minutes at 260°C, this film-like adhesive agent has a linear transmittance of 85% or greater for light at a wavelength of 400 to 800 nm. The thickness of this film-like adhesive agent is 10 to 40 µm. |
