PROBLEM TO BE SOLVED: To provide a resin substrate and a manufacturing method of the resin substrate which can prevent deformation due to a creep and maintain reliability of a connection with a terminal.SOLUTION: A resin substrate 10 has a core base material 11 and build-up layers 12 in which wirings 13, 13a, 13b are formed, and a terminal 200 which is electrically connected to the wirings 13, 13a, 13b by being pressed at a first terminal 210 and a second terminal 220. In the core base material 11 and the build-up layers 12, vias 14 and an interstitial via hole (IVH) 15 are formed between a contact part which is in contact with the first terminal 210 in the first wiring 13a and a contact part which is in contact with the second terminal 220 in the second wiring 13b. |
