To provide a seal component for a vehicle which includes an adhesive layer strongly adhering to and hardly separable from a seal component body and easily following to shape when attached to a complicatedly shaped member such as curve surface of the vehicle, and which makes it possible to mechanize/automate attachment work.SOLUTION: In a seal component for a vehicle which includes a weather strip body 2 and an attachment structure 6 which attaches an attached surface 5 of the weather strip body 2 to a member of the vehicle by intervening between the attached surface 5 and the member, at least attached surface 5 of the weather strip body 2 is composed of an olefinic rubber. The attachment structure 6 is constituted of modification surface 7 of which water contact angle formed on the attached surface 5 is 70° or less and an adhesive layer 8 which comprises a composition which contains styrene thermoplastic elastomer adhered on the modification surface 7 and a tackifier.SELECTED DRAWING: Figure 1 【課題】粘着層がシール部品本体に強く接着して剥離しにくく、また、乗物の曲面等の複雑形状の部材に貼り付けるときに形状追随が容易であり、貼り付け作業の機械化・自動化が可能になる乗物用シール部品を提供する。【解決手段】 ウエザストリップ本体２と、ウエザストリップ本体２の被着面５と乗物の部材との間に介在して該被着面５を該部材に貼り付ける貼付構造６とを有する乗物用シール部品において、ウエザストリップ本体２の少なくとも被着面５は、オレフィン系ゴムからなり、貼付構造６は、被着面５上に形成された水接触角が７０°以下である改質面７と、改質面７上に接着されたスチレン系熱可塑性エラストマー及び粘着付与剤を含む組成物からなる粘着層８とから構成される。【選択図】図１
