Polyimide resin precursor

A polyimide resin precursor comprising a structural unit represented by a following formula (1):

• wherein, in the formula (1), XA1 and YA1 are organic groups having 4 or more and 40 or less carbon atoms,
• RA1 and RA2 are each independently a hydrogen atom or an organic group having 1 or more and 30 or less carbon atoms, and the organic group as RA1 or RA2 bonds to an oxygen atom in an ester bond in the formula (1) through a C—O bond,
• having the organic group as RA1 or RA2, an unsaturated group G1 having 3 or more and 30 or less carbon atoms that does not comprise a (meth)acryloyl group but comprises one or more ethylenically unsaturated double bonds,
• optionally having a (meth)acryloyl group-containing group G2 as the organic group as RA1 or RA2,
• wherein a proportion of a sum of a number of moles of the unsaturated group G1 and a number of moles of the (meth)acryloyl group-containing group G2 to a total number of moles of the organic groups as RA1 and RA2 in the whole structural units is 60 mol % or more, and
• a proportion of the number of moles of the unsaturated group G1 to the total number of moles of the organic groups as RA1 and RA2 in the whole structural units is 10 mol % or more.
