A process for producing a lens comprising:

• a molding step of molding a mold having a plurality of shapes formed reversely to the transfer shape by repeating a transfer step more than once, wherein the transfer step includes:
• a transformation step of making contact between an article to be molded and a transfer member having a transfer shape formed equally to an aspherical lens portion and transforming the article to be molded to the transfer shape;
• a hardening step of hardening at least a transformed portion of the article to be molded;
• a separation step of separating the article to be molded and the transfer member from each other;
• and a moving step of moving the transfer member to another position of the article to be molded, wherein a pitch distance between positions for the transfer member to contact the article to be molded is changed in accordance with shrinkage of the article to be molded, the pitch distance being a distance between one position for transferring the transfer shape to the article to be molded and another position for transferring the transfer shape to the article to be molded that is adjacent to said one position;
• a lens array formation step of forming a lens array having a plurality of aspherical lens portions using said mold molded by the molding step;
• and
• a dividing step of dividing the lens array formed by the lens array formation step into a plurality of lenses having at least one aspherical lens portion.
