It looks like you are working with a 10-pin FPC connector (F-FPC1M10P-C310) that has a pitch of 1.00 mm. The pitch is the center-to-center distance between adjacent pins in a connector.

However, your question wasn't specific about which pins you're referring to. Do you have specific pin numbers in mind, or are you asking for the spacing between any two consecutive pins? If you are referring to consecutive pins, the distance would be equal to the pitch, which is 1.00 mm. If you're referring to pins that are not adjacent, please let me know the specific pin numbers, and I can help you calculate the distance.
