A laminated element manufacturing method includes a first forming step of forming a first gettering region for each of functional elements by irradiating a semiconductor substrate of a first wafer with a laser light, a first grindsing step of grinding the semiconductor substrate of the first wafer and removing a portion of the first gettering region, a bonding step of bonding a circuit layer of a second wafer to the semiconductor substrate of the first wafer, a second forming step of forming a second gettering region for each of the functional elements by irradiating the semiconductor substrate of the second wafer with a laser light, and a second grinding step of grinding the semiconductor substrate of the second wafer and removing a portion of the second gettering region.
