To suppress reduction of electrostatic capacitance and furthermore to improve withstand voltage of a capacitor component including an internal electrode provided in a porous main body.SOLUTION: A capacitor component 1 comprises: a porous main body 10 having a plurality of through-holes 11 extending in a first direction; a first internal electrode; and a second internal electrode. First grooves 12a, 12c, 12e, 12g are formed in the porous main body in such a manner that the first grooves penetrate the porous main body in the first direction and extend in a second direction orthogonal to the first direction. First electrode layers 23a to 23d included in the first internal electrode are embedded in the first grooves. Second grooves 12b, 12d, 12f, 12h each of which faces a first groove via a wall portion 13 are formed in the porous main body. Second electrode layers 24a to 24d included in the second internal electrode are embedded in the second grooves. Wall portions include at least two of the plurality of through-holes of the porous main body along a third direction orthogonal to the first direction and the second direction.SELECTED DRAWING: Figure 3 【課題】多孔性本体内に設けられた内部電極を有するキャパシタ部品において静電容量の低下を抑制しつつ耐電圧を向上させる。【解決手段】キャパシタ部品１は、第１方向に延びる複数の貫通孔１１を有する多孔性本体１０と、第１内部電極と、第２内部電極と、を備える。多孔性本体には、当該多孔性本体を第１方向に貫通しその第１方向と直交する第２方向に延びるように第１溝１２ａ、１２ｃ、１２ｅ、１２ｇが形成されている。第１内部電極に含まれる第１電極層２３ａ～２３ｄは、この第１溝に埋め込まれる。多孔性本体には、壁部１３を介して第１溝と対向する第２溝１２ｂ、１２ｄ、１２ｆ、１２ｈが形成されている。第２内部電極に含まれる第２電極層２４ａ～２４ｄは、この第２溝に埋め込まれる。壁部は、第１方向及び第２方向に直交する第３方向に沿って多孔性本体の複数の貫通孔のうちの少なくとも２つを含む。【選択図】図３
