Abstract
Provided are a wafer lens production method, an intermediate die, an optical component, a molding die, and a molding die production method. The production method of a wafer lens (1) includes a first intermediate die production step using a die (7), a second intermediate die production step using the first intermediate die (8), and a wafer lens production step using the second intermediate die (9). A first intermediate-die substrate (80) is provided with a depressed section (85) on the surface facing the die (7). When photo-curable resin (84A) is pressed, at least a portion closer to the first intermediate-die substrate (80) among the top (71a) and the peripheral section (77) of the die (7) is arranged in the depressed section (85), and a gap is provided so that the die (7) does not contact with a depressed plane (85a) of the depressed section (85).
