<p>Provided is a viscoelastic body that has small tack, is excellent in handleability, and generates a small amount of outgas even under a high-temperature condition. Also provided is a viscoelastic body that has small tack, is excellent in handleability, and exhibits excellent viscoelasticity in a wide temperature range of from low temperature to high temperature. A viscoelastic body according to one embodiment of the present invention has an outgas amount of 20 mg/cm3 or less when stored at 400° C. for 1 hour. A viscoelastic body according to another embodiment of the present invention has a G′in crimp type viscoelastic spectrum evaluation of 1.0×106 Pa or less in a temperature range of from−150° C. to 500° C.</p> |
