1. A photoelectric conversion element, comprising:
a first electrode section;
a second electrode section;
an electron-transporting section between the first electrode section and the second electrode section;
a light-absorbing section; and
a hole-transporting section comprising at least one hole transporting material having a spiro-ring structure and an oxidizing agent,
wherein the hole-transporting section has a peak that reaches maximum at a Raman shift of 1575 cm−1±10 cm−1 and a peak that reaches maximum at a Raman shift of 1606 cm−1±10 cm−1 in a Raman spectrum obtained by emitting laser light having a wavelength of 532 nm, and has a peak intensity ratio A/B of 0.90 or more, the peak intensity ratio A/B being obtained from a maximum peak intensity A of the peak that reaches maximum at 1575 cm−1±10 cm−1 and a maximum peak intensity B of the peak that reaches maximum at 1606 cm−1±10 cm−1.
