Patent ID: 7180007

Claim:
An electronic circuit device, comprising: a circuit board with a circuit pattern formed on a resin substrate by using conductive resin paste containing conductive particles and resin; a surface-mounted type electronic component arranged with an electrode terminal positioned with respect to a connecting region of the circuit pattern; a connecting member formed from the conductive resin paste disposed between the connecting region and the electrode terminal; and an insulating adhesive for bonding the electronic component to the circuit board, which is disposed in a space between the circuit board and the electronic component in the connecting region, having a curing temperature lower than that of the conductive resin paste, wherein a curing temperature of the conductive resin paste ranges from 80° C. to 110° C., and the curing temperature of the insulating adhesive is no lower than 50° C. and at least lower than the curing temperature of the conductive resin paste.
