    摘要： A mounting structure 1 in which an electronic component 5 is surface-mounted with solder 4 to a wiring substrate 2 is disclosed. The solder is Sn—Ag—Bi—In-based solder containing 0.1% by weight or more and 5% by weight or less of Bi, and more than 3% by weight and less than 9% by weight of In, with the balance being made up of Sn, Ag and unavoidable impurities. The wiring substrate has a coefficient of linear expansion of 13 ppm/K or less in all directions. Thus, it is possible to realize a mounting structure using lead-free solder and for which the occurrence of cracks in a solder joint portion due to a 1000-cycle thermal shock test from −40 to 150° C. has been suppressed.

    摘要： A brushless motor includes a stator having a stator core, a rotor, a circuit board, a board holder for holding the circuit board, a motor housing having a notch at an opening, and a housing cover. The motor housing accommodates the stator, the rotor, and the board holder to which the circuit board is mounted, and the motor housing is sealed with the housing cover. The board holder includes a board mount section, a lead-wire holder for holding lead-wires. The lead-wire holder is placed at the notch of the motor housing. The lead-wires extend from the circuit board mounted to the board mount section to the outside of the motor housing via the lead-wire holder.
