摘要:
A metal fine particle for a conductive metal paste includes a protective agent covering a surface of the metal fine particle. An amount of heat generated per unit mass (g) of the metal fine particle is not less than 500 J at a temperature of an external heat source temperature in a range of 200° C. to 300° C. when being calcined by the external heat source. The protective agent includes at least one selected from the group consisting of dipropylamine, dibutylamine, triethylamine, tripropylamine, tributylamine, butanethiol, pentanethiol, hexanethiol, heptanethiol, octanethiol, nonanethiol, decanethiol, undecanethiol and dodecanethiol. The content of the protective agent is in a range of 0.1 to 20% by mass with respect to the mass of the metal fine particle.

An insulating varnish includes a polyamide-imide resin varnish including a solvent and a polyamide-imide resin, and an organosol. The polyamide-imide resin varnish is obtained by a synthesis reaction between a resin component (X) and an isocyanate component (Y). The resin component (X) is obtained by a synthesis reaction between a diamine component and an acid component in presence of an azeotropic medium. The diamine component includes aromatic diamines including a divalent aromatic group having three or more aromatic rings. The isocyanate component (Y) includes a diisocyanate (Y1) a molecule of which includes a bend structure.

A collision detection system includes a shock detecting device, a collision position detecting device, a correcting device, and a collision determining device. The shock detecting device detects a magnitude of a shock due to a collision. The collision position detecting device detects a collision position of the collision. The correcting device corrects a detection result detected by the shock detecting device based on a detection result detected by the collision position detecting device. The collision determining device determines the collision based on a corrected result corrected by the correcting device.
