[Problem] To provide: an intravenous drip probe which is capable of detecting whether the probe is mounted upside-down on a drip chamber and of detecting a phenomenon where a drug dripping in the drip chamber splashes on the surface of the drug remaining inside the drip chamber so as to determine the accurate number of drops of the drug； and an infusion pump which is provided with the intravenous drip probe. [Solution] An intravenous drip probe (900) is used for an infusion pump (1) and is mounted on a drip chamber (810) to detect drops of the drug inside the drip chamber (810). The intravenous drip probe (900) comprises: a main body part (901)； a first sensor part (951) which is disposed inside the main body part (901) upstream with respect to the direction of dripping of the drug (750) inside the drip chamber (810) and detects drops of the drug； and a second sensor part (952) which is disposed inside the main body part (901) downstream of the first sensor part (951) with respect to the direction of dripping of the drug inside the drip chamber (810) and detects drops of the drug.
