A water absorbing agent includes water absorbent resin particles which are obtained by polymerizing a water-soluble ethylenic unsaturated monomer and which internally include a cross-linked structure, wherein a pressurized void average radius index is 140 or more. The device is characterized by including ribs disposed in the noise suppression element containing unit and arranged in such a way as to face the outer circumferential surface of the noise suppression element and a resin insulating material that is filled into the containing unit and makes contact with the ribs and the noise suppression element. No contact is formed above the Pt film used for forming an upper electrode, and the upper electrode is connected to an upper interconnect through the connection conductor film, a dummy lower electrode, a dummy cell plug and the local interconnect. The virtual IDE module includes an IDE host and an IDE device. In a more specific embodiment the filtering modes include polyphase filtering and general purpose filtering applications, and in another more specific embodiment the filtering modes include polyphase direct filtering, polyphase transposed filtering, and at least one general purpose filtering.
