摘要:
A laminate type electronic component 1 comprises, at least, a dielectric part 2 containing a dielectric as a constituent material, and a pair of a first external electrode 31 and a second external electrode 32, each disposed in close contact with the dielectric part 2, opposing each other by way of the dielectric part 2. The dielectric part 2 comprises laminated dielectric layers 21a to 21f; and at least two internal electrodes 23a to 23e disposed one by one between layers adjacent each other in the dielectric layers 21a to 21f, while each being electrically connected to one of the first external electrode 31 and second external electrode 32. At least one of the internal electrodes 23a to 23e is electrically connected to the first external electrode 31, and at least one of the internal electrodes 23a to 23e is electrically connected to the second external electrode 32. The first external electrode 31 and second external electrode 32 comprise resin electrode layers 31a and 32a, each made of a conductive resin mainly composed of a thermosetting resin and a conductive particle; a metal electrode layer 31b disposed between the resin electrode layer 31a and the dielectric part 2; and a metal electrode layer 32b disposed between the resin electrode layer 32a and the dielectric part 2. The conductive particle content in the conductive resin is 70 to 75 mass %, whereas the conductive particle contains, as a main ingredient, acicular particles 71 having an average longitudinal length of 30 to 70 μm and an aspect ratio of 1.5 to 3.3.
