PROBLEM TO BE SOLVED: To provide an inclination angle detection device for a saddle type vehicle capable of detecting a wider inclination angle of a saddle type vehicle, with precision and by a simple method.SOLUTION: An acceleration sensor 20, in a plane (y-z plane) regulated by a saddle type vehicle 1 car width direction (y-axis direction) and a vertical direction (z axis direction) of a saddle type vehicle 1, detects acceleration components XG, YG in two axes directions, of a first detection axis L1 having a detection axis which is a direction inclined by 45° relative to an axial line L0 orthogonal vertically to a pivot axis L arranged parallel to a car width direction and a second detection axis L2 having a detection axis which is the direction orthogonal to the first detection axis L1. A detection part C, based on the acceleration components XG, YG in two axes directions, detects inclination angle of the saddle type vehicle 1.
