Abstract

Method for producing a lens array, which can prevent a weld from being formed in the peripheral part of a lens part and suppress increase of a work time of a transfer mold, and a molding mold. Since a master moldof a molding mold has a plurality of linear groove partssurrounding a plurality of cavity parts, resin hardly spreads to a corner partwhere the adjacent linear groove partsandintersect each other and it is possible to prevent portions of the resin which have run over toward the adjacent groove partsandfrom spreading so as to come close to each other and being brought into contact with each other to create a weld trapping air bubbles.
