PROBLEM TO BE SOLVED: To provide a resin wiring board with pin in which connection pins are soldered to the pin-pad conductors of the resin wiring board and which is improved in the reliability of electrical characteristics. SOLUTION: The resin wiring board 1 with pin is provided with connections 6 (composed of via conductors) which electrically connect lid-like conductor layers 4 formed on a core substrate 2 having through hole conductors 22 and filling materials 23 in through holes 21 to the pin-pad conductors 5 provided with the connection pins 9 which can be connected to the connection terminals of an external substrate. Each connection 6 is constituted of a stacked via 6 in which via conductors 61 and 62 composed of field vias are connected to each other so that the conductors 61 and 62 may be ranged concentrically. At the same time, the stacked vias 6 and connection pins 9 are arranged so that their center axial lines 601 and 901 may become coincident with the center axial lines 201 of the through holes 21, when the penetrated directions of the through holes 21 are the directions of the center axial lines 201 of the through holes 21.
