Abstract

See full text

The present invention aims to provide resin particles that have excellent heat resistance and that, when used as base particles of conductive particles, are applicable to mounting by thermocompression bonding at low pressure to produce a connection structure having excellent connection reliability. The present invention also aims to provide conductive particles, a conductive material, and a connection structure each including the resin particles. Provided are resin particles having a 5% weight loss temperature of 350° C. or higher, a 10% K value at 25° C. of 100 N/mm2 or more and 2,500 N/mm2 or less, and a 30% K value at 25° C. of 100 N/mm2 or more and 1,500 N/mm2 or less.
