PROBLEM TO BE SOLVED: To provide an electronic component which allows for reduction of cutting load at the time of dicing.SOLUTION: An electronic component includes an elementary body having first and second end faces facing each other, and a top face connecting the first and second end faces, a circuit element embedded in the elementary body, a first extraction electrode embedded in the first end face side of the elementary body, and connected electrically to the circuit element, a columnar electrode placed while spaced apart from the first extraction electrode in the first direction, when viewed from a direction orthogonal to the first end face, and embedded in the elementary body so as to be exposed partially from the first end face to the top face, and a first via conductor connecting the first extraction electrode and the columnar electrode. When viewed from a direction orthogonal to the first end face, the exposure width of the first via conductor in the first end face, in a second direction orthogonal to the first direction, is smaller than that of the columnar electrode.SELECTED DRAWING: Figure 3 【課題】ダイシング時の切削負荷を低減できる電子部品を提供する。【解決手段】電子部品は、互いに対向する第１端面および第２端面と、第１端面と第２端面とを接続する上面と、を含む素体と、素体に埋め込まれた回路素子と、素体の第１端面側に埋め込まれ、回路素子と電気的に接続された第１引出電極と、第１端面に直交する方向からみて、第１引出電極から第１方向に離隔して配置され、第１端面から上面にかけて一部が露出するように素体に埋め込まれた柱状電極と、第１引出電極と柱状電極とを接続する第１ビア導体とを有し、第１端面に直交する方向からみて、第１方向に直交する第２方向に沿った第１端面における露出幅について、第１ビア導体の露出幅は、柱状電極の露出幅よりも小さい。【選択図】図３
