To provide a laminate which has remarkably improved adhesion between a rubber layer and a base material regardless of the kind of a component constituting the rubber layer or the kind of a material constituting the base material.SOLUTION: There is provided a laminate which a base material, an adhesive layer containing an acid modified polyolefin resin and a rubber layer are laminated in this order. When a polyolefin-based material is used as the base material, the laminate has a peel strength measured using a test piece cut into 20 mm width of 15 N/20 mm or more. The rubber layer is preferably composed of olefinic rubber.SELECTED DRAWING: None 【課題】ゴム層を構成する成分の種類、または基材を構成する材料の種類に関わらず、ゴム層と基材との接着性が顕著に向上された積層体を提供する。【解決手段】基材、酸変性ポリオレフィン樹脂を含有する接着剤層、およびゴム層がこの順に積層してなる積層体である。この積層体は、ポリオレフィン系材料を基材として用いた際に、２０ｍｍ巾に切り取った試験片を用いて測定された剥離強度が、１５Ｎ／２０ｍｍ以上である。ゴム層がオレフィン系ゴムからなることが好ましい。【選択図】なし
