Abstract: The invention relates to an image pickup optical system which can make a sensitive tradeoff between the precision of alignment of a decentration optical prism used as an image formation element for an electronic camera or the like with respect to an image pickup element and ease of fabrication. The invention provides an optical prism 100 comprising three optical surfaces 12 to 14. An entrance surface 14 is suitable for incidence of light from a subject. The incident light is subjected to at least two internal reflections to turn back an optical path. The reflected light leaves the prism through an exit surface 12 to form an image of the subject on an image pickup surface 21 located outside of the prism. At least one of the entrance surface 14 and exit surface 12 is constructed of an optical surface having a combined transmission and internal reflection action. The optical prism is used in combination with a prism frame 30 designed to be well fit therefor. Sides 60L and 60R formed in directions intersecting the directions of the entrance surface 14 and exit surface 12 are provided with protrusions 90L and 90R for mounting the optical prism 100 to the prism frame 30.
