Abstract
A noise protection sheet is stuck on an IC chip C loaded on a circuit board to control the noise generated from the IC chip C. The noise protection sheet includes a metallic sheet and insulating films sandwiching the metallic sheet from both front and rear surfaces thereof. The metallic sheet has, at its one end, an extending portion to be connected to a land serving as a grounding terminal on the circuit board In this configuration, the noise protection sheet can effectively solve a noise problem in an electronic component.
