1. A multilayer substrate module that has a filter function including an inductance component and a capacitance component, the multilayer substrate module comprising:
a first substrate portion including a first substrate portion body including a plurality of first insulator layers stacked in a vertical direction and a first conductor layer and/or a first interlayer connection conductor provided at the first substrate portion body;
a second substrate portion including a second substrate portion body including a plurality of second insulator layers stacked in the vertical direction and a second conductor layer and/or a second interlayer connection conductor provided at the second substrate portion body, the second substrate portion being mounted on an upper surface of the first substrate portion; and
a mount device mounted on an upper surface or a lower surface of the second substrate portion; wherein
at least a portion of the inductance component is defined by the first conductor layer and/or the first interlayer connection conductor provided in the first substrate portion;
the capacitance component is defined by the second conductor layer and/or the second interlayer connection conductor that is provided in the second substrate portion; and
a Young's modulus of a material of the plurality of second insulator layers is higher than a Young's modulus of a material of the plurality of first insulator layers.
