Abstract
(EN)
Provided is a silver powder including silver particles having closed pores inside the particles, wherein, when the cross-section of a silver particle is observed at a magnification of 10,000 times, the average number of pores having a Heywood diameter of 200 nm or larger with respect to the area of the cross-section is less than or equal to 0.01 pores/µm2, and when the cross-section of a silver particle is observed at a magnification of 40,000 times, the average number of pores having a Heywood diameter of 10 nm to less than 30 nm with respect to the area of the cross-section is greater than or equal to 25 pores/µm2.
