PROBLEM TO BE SOLVED: To provide an electronic control apparatus the lifetime of which can be enhanced by suppressing application of an excessive stress to junction of electronic components of a circuit board even when a force of deforming the circuit board in a planar direction is applied to the circuit board due to a temperature change. SOLUTION: The circuit board 11 mounted with the electronic components 10 is contained in a housing 1. Elastic members (columnar rubber members) 20 are arranged in the housing 1. The elastic members 20 are stood upright on the upper side of the circuit board 11 whose lower side is arranged in a slidable state, and arranged in a compressed state. The circuit board 11 is supported with the elastic members 20 for applying a biasing force F to the upper side of the circuit board 11 while deforming the circuit board 11 in the planar direction from a direction orthogonal to the upper side of the circuit board 11.
