Claim 0:
1. A multilayer substrate comprising:
a first insulating resin base material layer and a second insulating resin base material layer each including different materials; wherein
the second insulating resin base material layer is stacked on the first insulating resin base material layer on which a conductor film is formed;
an adhesion strength between the first insulating resin base material layer and the conductor film is higher than an adhesion strength between the second insulating resin base material layer and the conductor film; and
a difference between a linear expansion coefficient of the conductor film and a linear expansion coefficient of the first insulating resin base material layer is larger than a difference between a linear expansion coefficient of the conductor film and a linear expansion coefficient of the second insulating resin base material layer.
