PROBLEM TO BE SOLVED: To automatically determine which filling method it is when a filling method to a filling object vessel is different. SOLUTION: This liquefied gas filling device 60 includes a first pressure detector 131, a second pressure detector 132, a third pressure detector 133, a second opening-closing valve V2 and a third opening-closing valve V3. The respective pressure detectors 131-133 output a signal to a control circuit 90 as a detected pressure detecting signal. The control circuit 90 executes respective control programs by reading a control program A for determining whether to be a pressure equalizing filling method or a pushing-in filling method based on a comparing result and a control program B for controlling valve opening and opening-closing of a first opening-closing valve V1 and the second opening-closing valve V2 based on a determining result, from a memory 120, by comparing a first pressure value detected by the first pressure detector 131 with a second pressure value detected by the second pressure detector 132 in a state of closing the first opening-closing valve V1 by an input signal from a filling starting switch 94.
