The present invention provides a photosensitive resin composition for a biochip capable of forming a liquid-repellent film at high resolution with an alkaline aqueous solution without PEB treatment, a method for forming the liquid-repellent film, a method for producing a biochip, and the like. A photosensitive resin composition for a biochip, which is a composition containing the following polymer (A) or a composition containing the following polymer (B) and the following polymer (C), relative to the total number of units constituting the composition , containing 35 to 97 mol% of the following units (u2). Unit (u2): A unit represented by the following formula (II). Polymer (A): A polymer containing a unit (u1) and a unit (u2) having an organic group containing one or more fluorine atoms. Polymer (B): A polymer other than the polymer (A) containing a unit (u1) having an organic group containing one or more fluorine atoms. Polymer (C): A polymer other than the polymer (A) containing the unit (u2).
