Summary:PROBLEM TO BE SOLVED: To provide an inspection method for electrically verifying whether a spring and a terminal are in contact with each other in an appropriate position in design.SOLUTION: An inspection method of an electronic control device 200 which electrically connects an electronic component 25 with a terminal 51 via a conductive elastic member 52 includes: a voltage applying step of applying a voltage between the above terminal and a second terminal 21 electrically connected to the electronic component; a current value measurement step of measuring a current value of a current flowing from the terminal to the second terminal; a step of ensuring contact between the electronic component and the elastic member when a resistance value obtained from the applied voltage value and the current value is equal to or less than a first threshold; and a step of detecting a contact failure between the electronic component and the elastic member when the resistance value is not equal to or less than the first threshold.
