Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electronic part for preventing the exposure of a corner surface of an element and the generation of defective mounting surely. SOLUTION: The electronic part 1 includes an element 3 with an almost rectangular parallelepiped shape of 0.6 mm×0.3 mm×0.3 mm in dimension, and terminal electrodes 4A, 4B provided at both ends of the element 3. The terminal electrode 4A has a baking electrode layer 8A which covers the edge face 3a of the element 3 and turns from the edge face 3a to side faces 3c-3f through a corner 5. The terminal electrode 4B has a baking electrode layer 8B which covers an edge face 3b and turns from the edge face 3b to the side faces 3c-3f through the corner 5. Each curvature radius r of each corner 5 of the element 3 is 10-30 μm, the inequality T-R≤12 μm is satisfied where T is maximum thickness in dimension of the baking electrode layers 8A, 8B along the elongated direction of the element 3, and R is minimum thickness in dimension of the baking electrode layers 8A, 8B which concerns the corner 5 of the element 3.
