To provide an electromagnetic shielded electronic circuit board which suppresses unnecessary electromagnetic radiation from an electronic circuit and facilitates the inspection and repair of the electronic circuit and is advantageously made small-sized.

An electronic component 3 is put in the electromagnetic shield space between a board body 2 and an electromagnetic shield film 5. Consequently, the unnecessary electromagnetic radiation from the electronic component 3 to outside the electromagnetic shield film 5 can be suppressed, the board is not bulky as compared with a conventional sealed structure using a metallic box and can be made small sized, and the electromagnetic shielded electronic circuit board 1 can be inspected and repaired only by peeling the electromagnetic shield film 5.
