PROBLEM TO BE SOLVED: To provide an electronic circuit unit in where there is no rattling between a frame and a circuit board, and which can be mounted with accuracy, is small and inexpensive. SOLUTION: In the electronic circuit unit, a pair of mounting legs 2b located on the side wall 2 of a frame 1 has an arm 2e and a protrusion 2f positioned near the tip of the arm 2e, and the protrusion 2f elastically contacts with the wall inside the through hole 5a of the circuit board 5 to hold the circuit board 5, whereby, there is no rattling between the frame 1 and the circuit board 5, and the mounting position between the frame 1 and the circuit board 5 is fixed even in soldering etc. by reflowing. Therefore, the electronic circuit unit can be accurately mounted. Moreover, the tip of the arm 2e is flush with the circuit board 5 or slightly protrudes from the circuit board 5, whereby, the electronic circuit unit can be downsized in a upward/downward direction (a thickness direction).
