Abstract:
A multilayer substrate includes a base including insulating layers stacked on one another, a first principal surface, and a second principal surface, a heat transfer member extending through a first insulating layer nearest to the first principal surface, a second coefficient of thermal conductivity of a material of the heat transfer member is higher than a first coefficient of thermal conductivity of a material of the insulating layers, a first metal film adhered to the first principal surface, the first metal film overlapping the heat transfer member when viewed from the layer stacking direction, and a first joining member disposed between the heat transfer member and the first metal film and being made of a material with a coefficient of thermal conductivity which is higher than the first coefficient of thermal conductivity of the material of the insulating layers.

Claim (Index 19):
A method for manufacturing a multilayer substrate including a plurality of insulating layers stacked on one another in a layer stacking direction, and a via-hole conductor, the method comprising:\n a first step of forming a through-hole in a first insulating layer with a first metal film formed on a first principal surface such that the through-hole extends through the first insulating layer but does not extend through the first metal film, the first insulating layer being one of the plurality of insulating layers, the first principal surface being at an end in a first direction along the layer stacking direction; a second step of positioning a heat transfer member with a first joining member between the heat transfer member and the first metal film; and a third step of thermocompression bonding the plurality of insulating layers including the first insulating layer with the first insulating layer positioned at the end in the first direction along the layer stacking direction; wherein a material of the first joining member and a material of the via-hole conductor include tin; the heat transfer member is made of a material with a second coefficient of thermal conductivity which is higher than a first coefficient of thermal conductivity of a material of the first insulating layer; and the first joining member is made of a material with a third coefficient of thermal conductivity which is higher than the first coefficient of thermal conductivity.
