Silver powder and method of producing same

A method of producing a silver powder comprising:

• a milling step of using a pneumatic mill to accelerate and mill a silver powder produced by a wet reduction method;
• and
• a classification step of classifying the silver powder, performed after the milling step, wherein
• the milling step is performed with the silver powder having a powder concentration during milling of 0.2 kg/m3 or less,
• the classifying is performed such that after the classification step, the silver powder has powder physical properties of:
• a tap density of 4.8 g/mL or more;
• a TAP/D50 value that is a value determined by dividing the tap density by volume-based median diameter, in units of μm, of not less than 7 and not more than 15;
• and
• a specific surface area of not less than 0.75 m2/g and not more than 1.3 m2/g,
• a milling device in the milling step, a classifying device in the classification step, and a collecting device are connected in series in this order,
• an exhaust ventilator is connected at a downstream side of the collecting device and performs suction such that silver powder that has been supplied to the milling device is pneumatically conveyed to the collecting device, and
• a powder concentration during pneumatic conveyance determined by dividing a supply rate of silver powder in the milling step by an airflow rate of the exhaust ventilator is 0.08 kg/m3 or less.
