PROBLEM TO BE SOLVED: To provide an electronic circuit unit which fixes a shield case to a circuit board with good assemblability.SOLUTION: An electronic circuit unit 1 comprises: a circuit board C having a mounted electronic device C3 and penetrated through holes C1 and C2; and a shield case S which includes leg parts S1 and S2. To the through holes C1 and C2 of the circuit board C, the leg parts S1 and S2 of the shield case S are inserted and fixed, to cover the electronic device C3. Also, the through holes C1 and C2 include salient parts C10, C11, C20, C21, C22 and C23 which protrude to the inside. When the leg parts S1 and S2 of the shield case S are inserted into the through holes C1 and C2, the salient parts C10, C11, C20, C21, C22 and C23 are pressure welded to the leg parts S1 and S2, so that the shield case S is fixed to the circuit board C. |
