Disclosed is a method of manufacturing an electronic device, that includes obtaining a stack of the first electronic component and the second electronic component, while placing a resin layer which contains a flux-active compound and a thermosetting resin, between the first terminals and the second terminals; bonding the first terminals and the second terminals with solder, by heating the stack at a temperature not lower than the melting point of solder layers on the first terminals, while pressurizing the stack using a fluid; and curing the resin layer. The duration from the point of time immediately after the start of heating of the stack, up to the point of time when the temperature of the stack reaches the melting point of the solder layers, is set to 5 seconds or longer, and 15 minutes or shorter. |
