Abstract: Generation of outgassing is restrained to restrain deterioration in optical properties of a cover glass. A method for manufacturing an electronic device includes baking step of heating the cover glass on which an antireflection layer made of a cured product of a light-curing resin has been formed, an assembling step of installing the cover glass after the baking step at a position opposed to a light receiving surface of a sensor element to assemble a sensor module, and a reflow step of placing the sensor module on a mounting substrate and applying heat at a temperature of more than or equal to 250° C. to solder the sensor module to the mounting substrate. The baking step is performed before the reflow step to make a rate of generation of outgassing derived from a monomer having a monofunctional (meth)acryloyl group in outgassing generated from the antireflection layer of the cover glass in the reflow step less than or equal to 0.5% by mass relative to a mass of the antireflection layer.
