ELECTROMAGNETIC WAVE ABSORBER

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber which is easily manufactured and excellent in the electromagnetic wave absorbing performance. SOLUTION: The electromagnetic wave absorber includes resistors (a resistance film 4) on the whole surface of a sheet material 3A, and the surface resistance of the resistors is set to 380±100Ωper unit area. It includes lattice-like resistors on the whole surface of the sheet material 3A, and the resistance of each lattice-like resistor is set to 100±60Ω. The width of each lattice-like resistor is set to 2 mm, and the interval between adjacent resistors is set to 4 mm. The resistors are formed of the resistance film printed on the sheet material.
