Abstract

　優れた耐衝撃性と撮像機器の小型化・薄型化とを実現するため、本発明のアクチュエータは、撮像対象となる物体を結像する光学部材（１６）と、光学部材（１６）を保持するホルダ（１５）と、光学部材（１６）を光軸方向に移動するための磁気回路と、磁気回路を支持するベース（１８）とを備えている。磁気回路は、コイル（１４）及びマグネット（１２）を備え、コイル（１４）及びマグネット（１２）のうち一方がホルダ（１５）に取り付けられ、他方がベース（１８）に取り付けられている。ホルダ（１５）とベース（１８）との間隙には、球状体（１７）が配されており、球状体（１７）は、ホルダ（１５）の光軸方向の移動により、回転自在になっている。
