| Zusammenfassung: | A method for inspecting a laminated board, includes: performing a reflow process to solder an electronic component to a surface of a laminated board in which at least one of a plurality of wiring layers which are laminated with each other is coupled to another adjacent wiring layer via a via; and inspecting, in the reflow process, a conduction state of the via after a temperature of the laminated board reaches a melting point of a solder, and when the temperature of the laminated board is at a temperature range lower than the melting point and higher than room temperature. |
