Add Componets to several pages. Error | Ionic 4

Hello I have problem, I try add to several pages my Header Components (Ionic g component). My Header componet have a 4 files: html,scss,spec.ts and ts. When I add this component to minimum 2 pages I get this error:

Error: Type HeaderComponent is part of the declarations of 2 modules: Tab1PageModule and ProductPageModule! Please consider moving HeaderComponent to a higher module that imports Tab1PageModule and ProductPageModule. You can also create a new NgModule that exports and includes HeaderComponent then import that NgModule in Tab1PageModule and ProductPageModule.

Its my component look like this:

import { HeaderComponent } from './../../partials/header/header.component';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { Routes, RouterModule } from '@angular/router';

import { IonicModule } from '@ionic/angular';

import { ProductPage } from './product.page';

const routes: Routes = [
  {
    path: '',
    component: ProductPage
  }
];

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    IonicModule,
    RouterModule.forChild(routes)
  ],
  
  entryComponents:[HeaderComponent],
  declarations: [ProductPage,HeaderComponent]
})
export class ProductPageModule {}

I try several ways too add this component but I still stay on the same point. On one page works well.

I will be very greatful for help
