Imaging apparatus and distance measuring apparatus using the same

An imaging apparatus for capturing an image of a target object, comprising:

• lens optical systems each including a lens whose surface closest to the target object is shaped to be convex toward the target object;
• light detection cells which respectively face the lens optical systems;
• retainers each retaining the lens which is closest to the target object in each of the lens optical systems;
• and
• a cover which covers an exposed portion of the lens of each of the lens optical systems, the cover having a curved portion which is convex toward the target object, wherein:
• the surface of the lens which is closest to the target object in the imaging apparatus protrudes outwardly from the retainer toward the target object,
• the retainers are supported by a housing having a wall, and the wall is located between the light detection cells so as to separate spaces in which the light detection cells are disposed, respectively,
• in plan view, a convex center of the cover does not overlap the surface of the lens which is closest to the target object in each of the lens optical systems, and
• the light detection cells are provided in a single image sensor.
