<p>The purpose of the present invention is to provide a laminate wherein a non-fluorine rubber layer and a fluorine rubber layer are able to be firmly adhered to each other without using an adhesive and without subjecting the non-fluorine rubber layer and the fluorine rubber layer to a surface treatment. The present invention is a laminate which is provided with a fluorine rubber layer (B) and a non-fluorine rubber layer (A) that is laminated on the fluorine rubber layer (B). This laminate is characterized in that: the non-fluorine rubber layer (A) is formed from a non-fluorine rubber composition, and the non-fluorine rubber composition contains (a1) an unvulcanized non-fluorine rubber, (a2) at least one compound that is selected from the group consisting of 1,8-diazabicyclo(5.4.0)undecene-7 salts and 1,8-diazabicyclo(5.4.0)undecene-7, (a3) magnesium oxide and (a4) silica; and the fluorine rubber layer (B) is formed from a fluorine rubber composition that contains (b1) a fluorine rubber.</p> |
