PROBLEM TO BE SOLVED: To provide a metallic-lustrous laminated film for a key pad member excellent in radio-wave transmitting property and to provide a metallic-lustrous decorative film for the key pad member reduced in environmental load and excellent in recycling property. SOLUTION: The metallic-lustrous decorative film for the key pad member includes the laminated film in which 30 or more A layers 1 of thermoplastic resin layers and 30 or more B layers of thermoplastic resin layers are alternately laminated in a thickness direction. In the laminated film, a relative reflectance is 30-90% in wavelength bands of 400-1,000 nm, tensile stresses in film longitudinal and width directions are 3-90 MPa when extended by 100% in tension test at 150°C and having the number of the layers of 10-220 nm in thickness is larger than the number of layers of 220-320 nm in thickness.
