ホルダ13は、基板14の上に設けられ、ホルダ13の内部にレンズバレル12が組み込まれている。具体的には、レンズバレル12は、上部の円板部21と下部の嵌合部22とが接合された形状であり、嵌合部22は、側面が円周面となっている円筒形あるいは円柱形となっている。ホルダ13には、レンズバレル12の嵌合部22が嵌合される、上下方向に貫通した嵌合穴31が形成されている。
レンズバレル12は、結像用光学素子としての複数のレンズ(図示せず)を内部に備え、それらレンズによって、基板14に設けられたイメージセンサの面に、カメラモジュール1にて読み取られた像を結像するようになっている。
レンズバレル12の円板部21の上面における中央部には、焦点調整装置配置部(素子配置部)23が形成されている。この焦点調整装置配置部23は、焦点調整装置11の形状に対応した凹部形状に形成されている。本実施の形態において、焦点調整装置11は正方形の板状に形成されているので、焦点調整装置配置部23は正方形の凹部形状となっている。
電極端子24に対応して、レンズバレル12の円板部21の裏面には、図6に示すように、電極端子(レンズバレル第1電極端子)25が設けられている。図6は、レンズバレル12の底面を示す平面図である。4個の電極端子24の各々は、4個の電極端子25の対応するものと接続されている。
