PROBLEM TO BE SOLVED: To solve a problem that a conventional sheet material depends on absorption by heat loss and electromagnetic wave absorbing efficiency is not good when an electromagnetic wave flows in a conductive material using antennas as a current since the linear antennas are mutually independent. SOLUTION: In the electromagnetic wave absorbing material (insulating sheet 6), a plurality of linear antenna elements 5a are electrically connected by a connection pattern 5b. The connection pattern is made to be the sheet material 1 having a connection end part 5j for connecting one end 4a of a ground line 4.
