Claim Text:
1. A semiconductor module, comprising: a heat sink having conductivity; a power semiconductor chip located on a predetermined surface side of said heat sink; a low-power portion that is located on said predetermined surface side of said heat sink and has power consumption lower than that of said power semiconductor chip; a first plate-shaped insulating member extending between said power semiconductor chip and said heat sink; and a second plate-shaped insulating member extending between said low-power portion and said heat sink, wherein a portion, which faces said low-power portion, of said second plate-shaped insulating member is thicker than a portion, which faces said power semiconductor chip, of said first plate-shaped insulating member, said semiconductor module further comprising: a high-heat-resistant chip that is located on said predetermined surface side of said heat sink and has heat resistance higher than that of said power semiconductor chip; and a third plate-shaped insulating member extending between said high-heat-resistant chip and said heat sink, wherein a portion, which faces said high-heat-resistant chip, of said third plate-shaped insulating member is thicker than said portion, which faces said power semiconductor chip, of said first plate-shaped insulating member.
