发明名称 ELECTROMAGNETIC WAVE SHIELDING FILM, AND ELECTRONIC COMPONENT MOUNTING SUBSTRATE
摘要 <p>This electromagnetic wave shielding film (100) includes a base material layer (1) and an electromagnetic wave blocking layer (3) laminated to the base material layer (1). The electromagnetic wave blocking layer (3) is composed of at least one type of material selected from conductive materials and magnetic-absorbent materials, and has surface resistance of 1×10-3Ωto 1×10-6Ω, inclusive. With this electromagnetic wave shielding film (100), the electromagnetic wave blocking layer (3) can be lighter in weight and thinner, and electromagnetic waves in a high frequency band, such as one on the GHz order, can be effectively blocked. The light transmittance of the electromagnetic wave shielding film (100) at wavelengths of 300 nm to 800 nm, inclusive, is 0.01% to 30%, inclusive.</p>
