Provided is a method for manufacturing a touch panel sensor substrate that can be manufactured at a lower cost than a conventional manufacturing method and has excellent display quality without impairing visibility even when a metal material is used for a connection portion. The present application includes a first transparent electrode (1), a second transparent electrode (2), a first connection part (3), a second connection part (4), an insulating layer (5), and an extraction wiring (20). And a step of forming a first connection portion (3), a step of forming an insulating layer (5), and a first step. A step of forming the second connection portion (4), and the insulating layer (5) after one step of the step of forming the first connection portion (3) or the step of forming the second connection portion (4). And the other step of the step of forming the first connection portion (3) or the step of forming the second connection portion (4) after the step of forming the insulating layer (5). The reflectance of the second connection portion (4) and the lead-out wiring (20) is in the range of 0% to 30%.
