The invention relates to the technical field of temperature control sensing, in particular to a miniature flexibly packaged sensor, comprising a probe and a thermistor. The probe is a hollow tube withopenings at both ends. A hose clamp is arranged in the upper port of the probe. A packaging head is stuck on the hose clamp. The thermistor is inserted into the packaging head. Leads are soldered ontwo pins at the lower end of the thermistor. The pins, the leads, and the soldering parts of the pins and the leads are wrapped in insulating sleeves. The inner cavity of the probe is filled with a sealant. The miniature flexibly packaged sensor is reasonable in structure. A difficult-to-process profiled metal temperature-sensing probe is decomposed into a hollow tube probe and a teat-shaped packaging head, so as to reduce the processing difficulty, shorten the probe length, and save material. The teat-shaped silica gel packaging head can improve the response speed and the sensitivity of the internal thermistor. The el
