摘要： There are provided a solder joint structure, a power module using the joint structure, a power module substrate with a heat sink and a method of manufacturing the same, as well as a solder base layer forming paste which is disposed and fired on a metal member to thereby react with an oxide film generated on the surface of the metal member and form the solder base layer on the metal member, capable of suppressing the occurrence of waviness and wrinkles on the surface of the metal member even at the time of loading the power cycle and heat cycle and improving the joint reliability with a joint member.
