The purpose of the present invention is to provide an injector for an intraocular lens, whereby it is possible to easily set a lens support part to an appropriate position on a lens holder, and to safely carry out insertion work. A lens holder (404) is provided with a base part (441), a release-side guide part (442), and a passing part (443). A concave part (450) for housing the tip of a first lens support part (92) is formed on the release-side guide part (442). The concave part (450) holds the first lens support part (92) above the passing part (443). The release-side guide part (442) guides the first lens support part (92) along the circumference of an optical part (91).本發明提供一種眼內透鏡用注射器，其可簡單地將透鏡支承部設置於透鏡座之適當之位置，而可更安全地進行插入作業。透鏡座404具備台部441、放出側導引部442及通過部443。於放出側導引部442，形成有收容第1透鏡支承部92之前端之凹部450。藉由該凹部450將第1透鏡支承部92保持於較通過部443更靠上方。而且，藉由放出側導引部442，將第1透鏡支承部92以沿光學部91之圓周之方式導引。
