Abstract: Toner particles contain a non-crystalline polyester resin. The toner particles further contain 10 parts by mass to 30 parts by mass of a crystalline polyester resin, 30 parts by mass to 50 parts by mass of a styrene-acrylic acid-based resin, and 8 parts by mass to 15 parts by mass of an ester wax relative to 100 parts by mass of the non-crystalline polyester resin.

Abstract: A semiconductor module includes a semiconductor element having one and the other surface, a lead terminal connected electrically and thermally to the semiconductor element, a first solder which bonds the lead terminal and the one surface of the semiconductor element together, a circuit layer over which the semiconductor element is disposed and a second solder which bonds the other surface of the semiconductor element and the circuit layer together. The inequality (A/B)<1 holds, where A and B are the tensile strength of the first and second solder, respectively. As a result, even if the lead terminal which thermally expands because of heat generated by the semiconductor element expands or contracts toward the semiconductor element, a stress applied by the lead terminal is absorbed and relaxed by the first solder. This prevents damage to the surface electrode of the semiconductor element by suppressing the occurrence of cracks.
