Abstract: A manufacturing method for a sensor element includes a forming step. The forming step includes: a step (a) of forming an unfired electrode on one of plural green sheets; a step (b) of forming an unfired electrode lead and an unfired lead insulating layer on the same green sheet as in the step (a), the unfired electrode lead and to be connected to the unfired electrode, the unfired lead insulating layer surrounding at least part of the unfired electrode lead; and a step (c) of forming an unfired bonding layer so as to fill at least part of a region without the unfired lead insulating layer on the green sheet subjected to the step (b) and so as to overlap at least part of an edge portion of the unfired lead insulating layer.
