A wiring board comprising: a board core (11) having a core main surface (12) and a core reverse surface (13); a
capacitor (101, 101A, 101B, 101C, 101D, 101E, 101F, 101G, 101H, 101J, 1101, 1101′, 1101″, 1101′″, 1101″″, 1101′″″) having a
capacitor main surface (102) and a
capacitor reverse surface (103) and having a structure in which first inner
electrode layers (141) and second inner
electrode layers (142) are alternately laminated and arranged via a
dielectric layer (105), the capacitor (101, 101A, 101B, 101C, 101D, 101E, 101F, 101G, 101H, 101J, 1101, 1101′, 1101″, 1101′″, 1101″″, 1101′″″) being accommodated in the board core (11) in a state in which the core main surface (12) and the capacitor main surface (102) are oriented on a same side; and a wiring laminated portion (31) having a structure in which interlayer insulating
layers (33, 35) and conductor layers (42) are alternately laminated on the core main surface (12) and the capacitor main surface (102), wherein an
inductor (251, 252, 253) or a
resistor (301, 302, 311, 312, 321, 322) is formed on or in the capacitor (101, 101A, 101B, 101C, 101D, 101E, 101F, 101G, 101H, 101J, 1101, 1101′, 1101″, 1101′″, 1101″″, 1101′″″).
