摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorption composition which can surely form an electromagnetic wave absorption layer having enough electromagnetic wave absorption performance when it is held between two members. SOLUTION: The electromagnetic wave absorption composition is formed by mixing a loss material particle which consists of a magnetic material; a spacer particle which is hard enough not to crush to a prescribed minimum thickness or less even if it is held between two members, and has a particle diameter of the minimum thickness or more; and a bonding material which becomes a paste-like or clay-like mixture together with the loss material particle or the spacer particle. Since the particle diameter of the spacer particle is the minimum thickness or more, and the particle diameter of the loss material particle is the minimum thickness or less, the electromagnetic wave absorption layer with the minimum thickness or more can be readily and surely formed by holding the electromagnetic wave absorption composition between the two members.
