Claim 13:
14. A light irradiation system comprising:
a light irradiation device having an elongated outer shape, wherein
the light irradiation device includes:
an optical fiber configured to emit a light from a distal end of the optical fiber and including a curved part, the curved part orienting the distal end in a direction intersecting with a longitudinal direction of the light irradiation device; and
a light transmitting holder holding the curved part so as to maintain a shape of the curved part, wherein
the optical fiber includes a core, or the optical fiber includes the core and an outer surface layer, and
the holder has a refractive index lower than a refractive index of the core or a refractive index of the outer surface layer of the optical fiber; and

an elongated tubular catheter configured to receive the light irradiation device, wherein
the catheter includes:
a light transmitting portion configured to transmit light from inside the catheter to outside the catheter, at a position corresponding to the distal end of the optical fiber when the light irradiation device is inserted into the catheter.
