Summary:To provide a lens unit producing method capable for positioning a lens array with high precision over a long period of time, a lens array, and a lens unit. When the first flat surfaces LA1f come in contact with the respective tapered surfaces HLD1, the glass lens array LA1 cannot rotate more than that for the holder HLD. Meanwhile, since the tapered surfaces HLD1 are regulated by the respective opposite first flat surface LA1f, the glass lens array LA1 cannot move more than that relatively to the holder HLD. That is, by holding the glass lens array LA1 with the holder HLD, the glass lens array LA1 can be positioned with high precision for the holder HLD.
