PROBLEM TO BE SOLVED: To provide a method for manufacturing a microlens base plate by which the thickness of a resin layer can be made uniform. SOLUTION: The microlens base plate 1 has a 1st base plate (transparent base plate) 2 where a plurality of (many) recessed parts (recessed part of a microlens) 3 having a lens curved surface (concave surface) are formed, the resin layer 9 provided on the surface of the 1st base plate 2 where the recessed parts 3 are formed, a 2nd bas plate (surface layer) 8 provided on the resin layer 9, and a spacer 5 regulating the thickness of the resin layer 9, and a microlens 4 is formed of resin with which the recessed part 3 is filled in the resin layer 9. In the case of manufacturing the microlens base plate 1, the 1st base plate 2 and the 2nd base plate 8 are prepared and heated in advance. Unhardened resin is supplied to the surface of the 1st base plate 2 where the recessed parts 3 are formed, and the 1st and the 2nd base plates 2 and 8 are bonded via the resin under reduced pressure or in vacuum, then the resin is hardened to form the microlens 4 in the recessed part 3.
