PROBLEM TO BE SOLVED: To provide an adhesive having good dispersion of metal oxide particles, having a refractive index that can be adjusted to a high level, having good transparency and flexibility and showing substantially no decrease in the adhesive force with lapse of time.SOLUTION: The adhesive comprises a dispersant expressed by general formula (2) or general formula (3) and metal oxide particles having an average primary particle diameter of 5 to 100 nm. The metal oxide particles preferably contain at least an element selected from the group consisting of titanium, zinc, zirconium, antimony, indium, tin, aluminum and silicon. 【課題】本発明は、金属酸化物粒子の分散が良好であり、高い水準に屈折率を調整することが可能性あり、透明性および柔軟性が良好で、かつ接着力が経時後に低下し難い接着剤の提供を目的とする。【解決手段】一般式（２）または一般式（３）で示す分散剤、及び平均一次粒子径が５〜１００ｎｍの金属酸化物粒子を含有する接着剤であり、前記金属酸化物粒子が、チタニウム、亜鉛、ジルコニウム、アンチモン、インジウム、スズ、アルミニウム、および珪素からなる群から選ばれる少なくともいずれかであることが好ましい。【選択図】なし
